Note: I only transfer the constructor constraints, not the struct constraints. I think that's OK because the struct constraints are the same

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.
This patches depends on https://reviews.llvm.org/D130401 to use new added
SBDebugger::GetSetting() API for testing.

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

[clang-format] JSON formatting add new option for controlling newlines in json arrays
Working in a mixed environment of both vscode/vim with a team configured prettier configuration, this can leave clang-format and prettier fighting each other over the formatting of arrays, both simple arrays of elements.
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.
Happy to change the name of the option (this is the third name I tried)

In AIX OS, The default is to process 32-bit object files (ignore 64-bit objects). The mode can also be set with the OBJECT_MODE environment variable. For example, OBJECT_MODE=64 causes nm to process any 64-bit objects and ignore 32-bit objects. The -X flag overrides the OBJECT_MODE variable.

[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.

Here we want to place a hint "x:" on the expanded "1", but we shouldn't
be willing to place it on NUMBERS, because it doesn't *exactly*
correspond (it has more tokens).
Fortunately we don't even have to implement this algorithm from scratch,

[mlir] Add map_nested_foreach_thread_to_gpu_threads op to transform dialect
This revision adds a new op `map_nested_foreach_thread_to_gpu_threads` to transform dialect. The op searches `scf.foreach_threads` inside the `gpu_launch` and distributes them with `gpu.thread_id` attribute.
Loop mapping is explicit and given by the `map_nested_foreach_thread_to_gpu_threads` op. Mapping is done one-to-one, therefore the loops dissappear.
The dynamic trip count or trip count that are larger than thread size are not supported for the time being. However, we can indeed support them by generating a loop inside with cyclic scheduling.
For the time being, trip counts that are dynamic or bigger than thread sizes are not supported. However, in the future the compiler can indeed generate a loop with static cyclic scheduling to support these cases.
Current mechanism allows `scf.foreach_threads` to be siblings or nested. There cannot be interleaving code between the loops when they are nested.
