syntax for this (especially for all the default arguments) and we can let TableCheck check them
for consistency (e.g. an option with an optional argument can't have `eArgTypeNone`, naming of flags', etc.).

Also refactoring the related data structures can now be done without changing the hundred of option initializers.

For example, this line:
```
{LLDB_OPT_SET_ALL, false, "hide-aliases",         'a', OptionParser::eNoArgument, nullptr, {}, 0, eArgTypeNone, "Hide aliases in the command list."},
```
becomes this:
```
  def hide_aliases : Option<"hide-aliases", "a">, Desc<"Hide aliases in the command list.">;
```

For now I just moved a few initializers to the new format to demonstrate the change. I'll slowly migrate the other
option initializers tables  in separate patches.

[JSONCompilationDatabase] Strip distcc/ccache/gomacc wrappers from parsed commands.

Summary:
It's common to use compiler wrappers by setting CC="gomacc clang++".
This results in both args appearing in compile_commands.json, and clang's driver
can't handle this.

This patch attempts to recognize this pattern (by looking for well-known
wrappers) and dropping argv0 in this case.

It conservatively ignores other cases for now:
 - wrappers with unknown names
 - wrappers that accept -flags
 - wrappers where the compiler to use is implied (usually cc or gcc)

This is done at the JSONCompilationDatabase level rather than somewhere more
fundamental, as (hopefully) this isn't a general conceptual problem, but a messy
aspect of the nature of the ecosystem around compile_commands.json.
i.e. compilation databases more tightly tied to the build system should not have
this problem.

Enable compiler-rt on SPARC

This patch enables compiler-rt on SPARC targets. Most of the changes are straightforward:

- Add 32 and 64-bit sparc to compiler-rt

- lib/builtins/fp_lib.h needed to check if the int128_t and uint128_t types exist (which they don't on sparc)

There's one issue of note: many asan tests fail to compile on Solaris/SPARC:

fatal error: error in backend: Function "_ZN7testing8internal16BoolFromGTestEnvEPKcb": over-aligned dynamic alloca not supported.

Therefore, while asan is still built, both asan and ubsan-with-asan testing is disabled. The
goal is to check if asan keeps compiling on Solaris/SPARC. This serves asan in gcc,
which doesn't have the problem above and works just fine.

With this patch, sparcv9-sun-solaris2.11 test results are pretty good:

Failing Tests (9):
    Builtins-sparc-sunos :: divtc3_test.c
    Builtins-sparcv9-sunos :: compiler_rt_logbl_test.c

There is not match for the `MipsJmpLink texternalsym` and `MipsJmpLink
tglobaladdr` patterns for microMIPS R6. As a result LLVM incorrectly
selects the `JALRC16` compact 2-byte instruction which takes a target
instruction address from a register only and assign `R_MIPS_32` relocation
for this instruction. This relocation completely overwrites `JALRC16`
and nearby instructions.

This patch adds missed matching patterns, selects `BALC` instruction and
assign a correct `R_MICROMIPS_PC26_S1` relocation.

[YAMLIO] Remove trailing spaces when outputting maps

llvm::yaml::Output::paddedKey unconditionally outputs spaces, which
are superfluous if the value to be dumped is a sequence or map.
Change `bool NeedsNewLine` to `StringRef Padding` so that it can be
overridden to `\n` if the value is a sequence or map.

An empty map/sequence is special. It is printed as `{}` or `[]` without
a newline, while a non-empty map/sequence follows a newline. To handle
this distinction, add another variable `PaddingBeforeContainer` and does
the special handling in endMapping/endSequence.

[Driver] Refactor interaction between -f(no-)?omit-frame-pointer and -m(no-)?omit-leaf-frame-pointer

Use a tri-state enum to represent shouldUseFramePointer() and
shouldUseLeafFramePointer().

This simplifies the logic and fixes PR9825:
  -fno-omit-frame-pointer doesn't imply -mno-omit-leaf-frame-pointer.

and PR24003:
  /Oy- /O2 should not omit leaf frame pointer: this matches MSVC x86-32.
  (/Oy- is a no-op on MSVC x86-64.)

and:
  when CC1 option -mdisable-fp-elim if absent, -momit-leaf-frame-pointer
  can also be omitted.

The new behavior matches GCC:
  -fomit-frame-pointer wins over -mno-omit-leaf-frame-pointer
  -fno-omit-frame-pointer loses out to -momit-leaf-frame-pointer

The behavior makes lots of sense. We have 4 states:

- 00) leaf retained, non-leaf retained
- 01) leaf retained, non-leaf omitted  (this is invalid)
- 10) leaf omitted, non-leaf retained  (what -momit-leaf-frame-pointer was designed for)
- 11) leaf omitted, non-leaf omitted

"omit" options taking precedence over "no-omit" options is the only way
to make 3 valid states representable with -f(no-)?omit-frame-pointer and
-m(no-)?omit-leaf-pointer.
