Fix placement of forced local symbols in the dynamic symbol table.

Fix problem where version script causes predefined hidden symbol to be defined twice.
When creating a predefined hidden symbol like _GLOBAL_OFFSET_TABLE_, gold
was incorrectly letting a version script add a version to the symbol,
resulting in two copies of the symbol, both STB_LOCAL, but one of which
was grouped in the globals part of the symbol table.

Class-ify ui_out
This patch finalizes the C++ conversion of the ui-out subsystem, by
turning the ui_out and ui_out_impl structures into a single class
hierarchy. ui_out functions are turned into virtual methods of that new
class, so as a result there are a lot of call sites to update.
In the previous version of the patchset, there were separate ui_out and
ui_out_impl classes, but it wasn't really useful and added boilerplate.
In this version there is simply an ui_out base class that is
extended for CLI, TUI and MI.
It's a bit hard to maintain a ChangeLog for such a big patch, I did my
best but I'm sure there are some missing or outdated info in there...

Support aligning text section from odd addresses
Previously, the alignment directives were not correctly supported
in the text section when current alignment was only 1 byte (i.e.,
when the address was odd). Since there are no 1-byte instructions
in RISC-V, this patch resolves the bug by writing a zero byte to
obtain 2-byte alignment, at which point a 2-byte NOP can be used
to obtain 4-byte alignment.

Fix longjmp across readline w/ --enable-sjlj-exceptions toolchains
Nowadays, GDB propagates C++ exceptions across readline using
setjmp/longjmp
89525768cd08 ("Propagate GDB/C++ exceptions across
readline using sj/lj-based TRY/CATCH") because DWARF-based unwinding
can't cross C functions compiled without -fexceptions (see details
from the commit above).
Unfortunately, toolchains that use SjLj-based C++ exceptions got
broken with that fix, because _Unwind_SjLj_Unregister, which is put at
the exit of a function, is not executed due to the longjmp added by
that commit.

Re-work RISC-V gas flags: now we just support -mabi and -march
We've decided to standardize on two flags for RISC-V: "-march" sets the
target architecture (which determines which instructions can be
generated), and "-mabi" sets the target ABI. We needed to rework this
because the old flag set didn't support soft-float or single-float ABIs,
and didn't support an x32-style ABI on RISC-V.
Additionally, we've changed the behavior of the -march flag: it's now a
lot stricter and only parses things we can actually understand.
Additionally, it's now lowercase-only: the rationale is that while the
RISC-V ISA manual specifies that ISA strings are case-insensitive, in
Linux-land things are usually case-sensitive. Since this flag can be
used to determine library paths, we didn't want to bake some
case-insensitivity in there that would case trouble later.
This patch implements these two new flags and removes the old flags that
could conflict with these. There wasn't a RISC-V release before, so we
want to just support a clean flag set.

Rework RISC-V relocations
Before this commit we didn't cleanly support CFI directives because the
internal offsets used to get relaxed which broke them. This patch
significantly reworks how we handle linker relaxations:
* DWARF is now properly supported
* There is a ".option norelax" to disable relaxations, for when users
write assembly that can't be relaxed (if it's to be later patched up,
for example).
* There is an additional _RELAX relocation that specifies when previous
relocations can be relaxed.
We're in the process of documenting the RISC-V ELF ABI, which will
include documentation of our relocations
https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md
but we expect that this relocation set will remain ABI compatible in the
future (ie, it's safe to release).
Thanks to Kuan-Lin Chen for figuring out how to correctly relax the
debug info!

Fix edge cases in orphan section placement.
There were still some cases I found where orphan section placement
was screwy -- where the script has no output section description for
either .data or .bss, a .bss orphan section ends up getting placed
before the .data section. In addition, if there is an output section
description for a data section not named .data (e.g., .rela.dyn),
the orphan .bss gets placed before it. This patch cleans that up,
by tracking the last allocated section even as we're adding orphans.
I've also improved segment layout in the absence of a PHDRS clause.
A zero-length NOBITS section will no longer force a new segment
when followed by a PROGBITS section.

Fix problems with bss handling in linker scripts.
PR 16711 noted that gold allocates file space for BSS sections when using
a linker script. I've fixed that by rewriting set_section_addresses and
set_section_list_addresses to track the file offset separate from the
current virtual address, so that BSS sections do not move the file offset.
Now, if a series of BSS sections come at the end of a segment, we do not
allocate file space; but if a script forces them into the middle of a
segment, we will still allocate file space (matching Gnu ld behavior).
I've also added a warning when that happens.
That exposed another problem where orphan .bss sections were sometimes
placed in the middle of a segment. For example, if the script mentions
the .got section, but both .data and .bss are orphans, gold would put
both .data and .bss in front of .got. I've fixed that by ensuring that
orphan BSS sections are always placed after all other allocated sections.
It also exposed a problem where the SUBALIGN property is not handled
properly. The ld manual clearly states that it should override input section
alignment, whether greater or less than the given alignment, but gold would
only increase an input section's alignment. Gold would also place the output
section based on its original alignment before the SUBALIGN property took
effect, leading to a misaligned output section (where the input section
was properly aligned in memory, but was not aligned relative to the start
of the section), in violation of the ELF/gABI spec. I've fixed that by
making sure that the SUBALIGN property overrides the internal alignment of
the input sections as well as the external alignment of the output section.
This affected the behavior of script_test_2, which was written to expect
a misaligned section.
The net effect is, I think, improved compatibility with the BFD linker.
There are still cases where orphan placement differs, but the differences
should be rarer and less important. ALIGN and SUBALIGN behavior is closer,
but still not an exact match -- I still found cases where ld would create
a misaligned output section, and where gold will properly align it.

MIPS16: Remove unused `>' operand code
This code has never been used throughout the repository history, and
likely not before either, as due to the assymetry of MIPS16 instruction
set encoding there are no 32-bit shift operations having their immediate
shift count placed in the position of the usual `rx' instruction field.

MIPS16/opcodes: Use hexadecimal interpretation for the `e' operand code
Make the `e' operand code used with raw EXTEND instructions use the
hexadecimal rather than decimal format, for consistency with what is
actually produced by code in `print_insn_mips16' dedicated to EXTEND
disassembly. Due to that special handling the operand code is only
interpreted for assembly however, which accepts either format either
way, so there is no functional change here.
