[mlir][gpu] Fix crash in `gpu-module-to-binary` (#75477)
This patch fixes the error in issue #75434. The crash was being caused
by not checking for a lack of target attributes in a GPU module. It's
now considered an error to invoke the pass with a GPU module with no
target attributes.

[Sema] atomic_compare_exchange: check failure memory order (#74959)
For
`__atomic_compare_exchange{,_n}/__c11_atomic_compare_exchange_{strong,weak}`,
GCC checks both the success memory order and the failure memory order
under the default -Winvalid-memory-model ("memory model" is confusing
here and "memory order" is much more common in the atomic context).
* The failure memory order, if a constant, must be one of
relaxed/consume/acquire/seq_cst.
Clang checks just the success memory order under the default
-Watomic-memory-ordering. This patch checks the failure memory order.

Fix a crash from character type confusion interaction with libedit (#75388)
If you type `settings show <tab>` LLDB might crash, depending on the
version of libedit you're compiled with, and whether you're compiled
with `-DLLDB_EDITLINE_USE_WCHAR=0` (and depending on how the optimizer
lays out the stack...)
The issue has to do with trying to figure out whether the libedit
`getchar` callback is supposed to read a wide or 8 bit character. In
order to maintain backward compatibility, there's really no 'clean' way
to do it. We just have to make sure that we're invoking el_[w]getc with
a buffer that is as wide as the getchar callback (registered by the
`SetGetCharacterFunction` function further down in `Editline.cpp`.
So, it's 'fixed' with a comment, and a wider version of the 'reply'
variable.

[Profile] Add binary profile correlation for code coverage. (#69493)
## Motivation
Since we don't need the metadata sections at runtime, we can somehow
offload them from memory at runtime. Initially, I explored [debug info
correlation](https://discourse.llvm.org/t/instrprofiling-lightweight-instrumentation/59113),
which is used for PGO with value profiling disabled. However, it
currently only works with DWARF and it's be hard to add such artificial
debug info for every function in to CodeView which is used on Windows.
So, offloading profile metadata sections at runtime seems to be a
platform independent option.
## Design
The idea is to use new section names for profile name and data sections
and mark them as metadata sections. Under this mode, the new sections
are non-SHF_ALLOC in ELF. So, they are not loaded into memory at runtime
and can be stripped away as a post-linking step. After the process
exits, the generated raw profiles will contains only headers + counters.
llvm-profdata can be used correlate raw profiles with the unstripped
binary to generate indexed profile.
## Data
For chromium base_unittests with code coverage on linux, the binary size
overhead due to instrumentation reduced from 64M to 38.8M (39.4%) and
the raw profile files size reduce from 128M to 68M (46.9%)

```
A few things to note:
1. llvm-profdata doesn't support filter raw profiles by binary id yet,
so when a raw profile doesn't belongs to the binary being digested by
llvm-profdata, merging will fail. Once this is implemented,
llvm-profdata should be able to only merge raw profiles with the same
binary id as the binary and discard the rest (with mismatched/missing
binary id). The workflow I have in mind is to have scripts invoke
llvm-profdata to get all binary ids for all raw profiles, and
selectively choose the raw pnrofiles with matching binary id and the
binary to llvm-profdata for merging.
2. Note: In COFF, currently they are still loaded into memory but not
used. I didn't do it in this patch because I noticed that `.lcovmap` and
`.lcovfunc` are loaded into memory. A separate patch will address it.
3. This should works with PGO when value profiling is disabled as debug
info correlation currently doing, though I haven't tested this yet.

[lldb] Remove PopPlan asserts and skip test on Arm/AArch64 Linux
This reverts commit 481bb62e50317cf20df9493aad842790162ac3e7 and
71b4d7498ffecca5957fa0a63b1abf141d7b8441, along with the logging
and assert I had added to the test previously.
Now that I've caught it failing on Arm:
https://lab.llvm.org/buildbot/#/builders/17/builds/46598
Now I have enough to investigate, skip the test on the effected
platforms while I do that.
