[llvm-rc] [test] Fix the windres-preproc test with other mingw triple forms. NFC.
When invoking the preprocessor, llvm-windres produces a mingw
triple; if the llvm default target triple is a mingw target, it
is used as is - if not, a mingw style triple is generated.
Relax the testcase, to not strictly require "w64" as vendor (allow
the vendor field to be missing entirely), and allow both
"mingw32" and "windows-gnu" as OS/environment (where both forms are
common, while the latter is the normalized form).

[clang] [Driver] Do not transform explicit --config filename
Disable transformations (e.g. attempting to replace target architecture)
in the config filename that is passed explicitly via `--config`. This
behavior is surprising and confusing -- if user passes an explicit
config filename, Clang should use it as is. The transformations are
still applied when the name is deduced from filename.
Update the tests accordingly. This primarily ensures that full filename
with .cfg suffix is passed to --config (appending `.cfg` implicitly is
not documented, and would collide with use of filenames with other
suffixes). The config-file2.c suite is removed entirely as it tested
the transformations on the argument to --config. However, the aspects
of that that were not tested as part of config-file3.c are now added
there (based on config filename deduced from executable).
This change streamlines the code in Driver::loadConfigFile(), opening
the possibility of further changes, including support for handling
multiple --config options and refactoring of filename deduction.

we catch it anyway. So (hopefully) that should be more efficient without sacrificing correctness.

Add auto deduce source map setting
This patch adds a new "target.auto-source-map-relative" setting.
If enabled, this setting may auto deduce a source map entry based on requested
breakpoint path and the original path stored in debug info for resolved
breakpoint.
As an example, if debug info contains "./a/b/c/main.cpp", user sets a source
breakpoint at "/root/repo/x/y/z/a/b/c/main.cpp". The breakpoint will resolve
correctly now with Greg's patch https://reviews.llvm.org/D130401. However, the
resolved breakpoint will use "./a/b/c/main.cpp" to locate source file during
stop event which would fail most of the time.
With the new "target.auto-source-map-relative" setting enabled, a auto deduced
source map entry "." => "/root/repo/x/y/z" will be added. This new mapping will
help lldb to map resolved breakpoint path "./a/b/c/main.cpp" back to
"/root/repo/x/y/z/a/b/c/main.cpp" and locate it on disk.
If an existing source map entry is used the patch also concatenates the auto
deduced entry with any stripped reverse mapping prefix (see example below).
As a second example, debug info contains "./a/b/c/main.cpp" and user sets
breakpoint at "/root/repo/x/y/z/a/b/c/main.cpp". Let's say there is an existing
source map entry "." => "/root/repo"; this mapping would strip the prefix out of
"/root/repo/x/y/z/a/b/c/main.cpp" and use "x/y/z/a/b/c/main.cpp" to resolve
breakpoint. "target.auto-source-map-relative" setting would auto deduce a new
potential mapping of "." => "x/y/z", then it detects that there is a stripped
prefix from reverse mapping and concatenates it as the new mapping:
"." => "/root/repo/x/y/z" which would correct map "./a/b/c/main.cpp" path to
new path in disk.

SBDebugger::GetSetting() API for testing.

[LV] Keep track of cost-based ScalarAfterVec in VPWidenPointerInd.
Epilogue vectorization uses isScalarAfterVectorization to check if
widened versions for inductions need to be generated and bails out in
those cases.
At the moment, there are scenarios where isScalarAfterVectorization
returns true but VPWidenPointerInduction::onlyScalarsGenerated would
return false, causing widening.
This can lead to widened phis with incorrect start values being created
in the epilogue vector body.
This patch addresses the issue by storing the cost-model decision in
VPWidenPointerInductionRecipe and restoring the behavior before 151c144.
This effectively reverts 151c144, but the long-term fix is to properly
support widened inductions during epilogue vectorization
Fixes #57712.

[lldb] Reset breakpoint hit count before new runs
A common debugging pattern is to set a breakpoint that only stops after
a number of hits is recorded. The current implementation never resets
the hit count of breakpoints; as such, if a user re-`run`s their
program, the debugger will never stop on such a breakpoint again.
This behavior is arguably undesirable, as it renders such breakpoints
ineffective on all but the first run. This commit changes the
implementation of the `Will{Launch, Attach}` methods so that they reset
the _target's_ breakpoint hitcounts.

This review aims to add some "control knobs" to the Json formatting in clang-format to help align the two tools so they can be used interchangeably.
This will allow simply arrays `[1, 2, 3]` to remain on a single line but will break those arrays based on context within that array.

[libc++] Always query the compiler to find whether a type is always lockfree
In https://llvm.org/D56913, we added an emulation for the __atomic_always_lock_free
compiler builtin when compiling in Freestanding mode. However, the emulation
did (and could not) give exactly the same answer as the compiler builtin,
which led to a potential ABI break for e.g. enum classes.
After speaking to the original author of D56913, we agree that the correct
behavior is to instead always use the compiler builtin, since that provides
a more accurate answer, and __atomic_always_lock_free is a purely front-end
builtin which doesn't require any runtime support. Furthermore, it is
available regardless of the Standard mode (see https://godbolt.org/z/cazf3ssYY).
However, this patch does constitute an ABI break. As shown by https://godbolt.org/z/1eoex6zdK:
- In LLVM <= 11.0.1, an atomic<enum class with 1 byte> would not contain a lock byte.
- In LLVM >= 12.0.0, an atomic<enum class with 1 byte> would contain a lock byte.
This patch breaks the ABI again to bring it back to 1 byte, which seems
like the correct thing to do.
