In this patch I merged a few test cases with their YAMLs from Inputs

[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

    UBSan-Standalone-sparc :: TestCases/TypeCheck/misaligned.cpp

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.

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.

Summary:
There's no real reason to use clang-cl on Windows, the clang driver
works just as well. This fixes a test which uses the -O0 flag, which was
recently removed from clang-cl to match MSVC, which lacks this flag.

While I'm here, remove the explicit -std=c++11 flag. Previously, this
flag was necessary when the default C++ standard was C++98. Now that the
default is C++14, this is no longer necessary. It's problematic on
Windows, because the Visual C++ standard library relies on C++14
features, and attempting to compile it with C++11 results in errors.
Rather than adding logic to conditionally set the standard to C++11 only
on non-Win, this flag can be removed.

[lldb] Make TestDeletedExecutable more reliable

Summary:
It seems that calling Popen can return to the caller before the started process has read all the needed information
from its executable. This means that in case we delete the executable while the process is still starting up,
this test will create a zombie process which in turn leads to a failing test. On my macOS system this happens quite frequently.

This patch fixes this by letting the test synchronize with the inferior after it has started up.

[lldb] Don't use __FUNCTION__ as a file name

Summary:
I saw while debugging that we call this file `ParseInternal`, which is not a very good name for our
fake expression file and also adds this unnecessary link between the way we name this function
and the other source location names we get from the expression parser. This patch is renaming
it to `<lldb-expr>` which is closer to the way Clang names its buffers, it doesn't depend on the
function name (which changes when I refactor this code) and it's easier to grep for.

Summary:
Adds the following two options to lld-link:

-thinlto-prefix-replace: allows replacing a prefix in paths generated
for ThinLTO. This can be used to ensure index files and native object
files are stored in unique directories, allowing multiple distributed
ThinLTO links to proceed concurrently.

-thinlto-object-suffix-replace: allows replacing a suffix in object
file paths involved in ThinLTO. This allows minimized index files to
be used for the thin link while storing the paths to the full bitcode
files for subsequent steps (code generation and final linking).

IDE/clangd replace auto with whatever type clangd thinks it is. In case
of long/complext types this makes is reduces writing effort for the
