[CUDA, NVPTX] Added basic __bf16 support for NVPTX.
Recent Clang changes expose _bf16 types for SSE2-enabled host compilations and
that makes those types visible furing GPU-side compilation, where it currently
fails with Sema complaining that __bf16 is not supported.
Considering that __bf16 is a storage-only type, enabling it for NVPTX if it's
enabled on the host should pose no issues, correctness-wise.
Recent NVIDIA GPUs have introduced bf16 support, so we'll likely grow better
support for __bf16 on NVPTX going forward.

[trace][intel pt] Simple detection of infinite decoding loops
The low-level decoder might fall into an infinite decoding loop for
various reasons, the simplest being an infinite direct loop reached due
to wrong handling of self-modified code in the kernel, e.g. it might
reach
```
0x0A: pause
0x0C: jump to 0x0A
```
In this case, all the code is sequential and requires no packets to be
decoded. The low-level decoder would produce an output like the
following
```
0x0A: pause
0x0C: jump to 0x0A
0x0A: pause
0x0C: jump to 0x0A
0x0A: pause
0x0C: jump to 0x0A
... infinite amount of times
```
These cases require stopping the decoder to avoid infinite work and signal this
at least as a trace error.
- Add a check that breaks decoding of a single PSB once 500k instructions have been decoded since the last packet was processed.
- Add a check that looks for infinite loops after certain amount of instructions have been decoded since the last packet was processed.
- Add some `settings` properties for tweaking the thresholds of the checks above. This is also nice because it does the basic work needed for future settings.
- Add an AnomalyDetector class that inspects the DecodedThread and the libipt decoder in search for anomalies. These anomalies are then signaled as fatal errors in the trace.
- Add an ErrorStats class that keeps track of all the errors in a DecodedThread, with a special counter for fatal errors.
- Add an entry for decoded thread errors in the `dump info` command.
Some notes are added in the code and in the documention of the settings,
so please read them.
Besides that, I haven't been unable to create a test case in LLVM style, but
I've found an anomaly in the thread #12 of the trace
72533820-3eb8-4465-b8e4-
4e6bf0ccca99 at Meta. We have to figure out how to
artificially create traces with this kind of anomalies in LLVM style.
With this change, that anomalous thread now shows:
```

[AArch64][ARM] Alter v8.1a neon intrinsics to be target-based, not preprocessor based
As a continuation of D132034, this switches the QRDMX v8.1a neon
intrinsics over from preprocessor defines to be target-gated. As there
is no "rdma" or "qrdmx" target feature, they use the "v8.1a"
architecture feature directly.
This works well for AArch64, but something needs to be done for Arm at
the same time, as they both use the same header and tablegen emitter.
This patch opts for adding "v8.1a" and all dependant target features to
the Arm TargetParser, similar to what was recently done for AArch64 but
through initFeatureMap when the Architecture is parsed. I attempted to
make the code similar to the AArch64 backend.

[IncludeCleaner] Handle more C++ constructs
Summary:
This brings IncludeCleaner's reference discovery from AST to the parity
with current implementation in clangd. Some highlights:
- Handling of MemberExprs, only the member declaration is marked as
referenced and not the container, unlike clangd.
- Constructor calls, only the constructor and not the container, unlike
clangd.
- All the possible candidates for unresolved overloads, same as clangd.
- All the shadow decls for using-decls, same as clangd.
- Declarations for definitions of enums with an underlying type and
functions, same as clangd.
- Using typelocs, using templatenames and typedefs only reference the
found decl, same as clangd.
- Template specializations only reference the primary template, not the
explicit specializations, to be fixed.
- Expr types aren't marked as used, unlike clangd.
Going forward, we can consider having signals to indicate type of a
reference (e.g. `implicit` signal for type of an expr) so that the
applications can perform a filtering based on their needs.
At the moment the biggest discrepancy is around type of exprs, i.e. not
marking containers for member/constructor accesses. I believe this is
the right model since the declaration of the member and the container
should be available in a single file (modulo macros).

Fix breakpoint setting so it always works when there is a line entry in a compile unit's line table.
Prior to this fix, if the compile unit function:
void CompileUnit::ResolveSymbolContext(const SourceLocationSpec &src_location_spec, SymbolContextItem resolve_scope, SymbolContextList &sc_list);
was called with a resolve scope that wasn't just eSymbolContextLineEntry, we would end up calling:
line_entry.range.GetBaseAddress().CalculateSymbolContext(&sc, resolve_scope);
This is ok as long as the line entry's base address is able to be resolved back to the same information, but there were problems when it didn't. The example I found was we have a file with a bad .debug_aranges section where the address to compile unit mapping was incomplete. When this happens, the above function call to calculate the symbol context would end up matching the module and it would NULL out the compile unit and line entry, which means we would fail to set this breakpoint. We have many other clients that ask for eSymbolContextEverything as the resolve_scope, so all other locations could end up failing as well.
The solutions is to make sure the compile unit matches the current compile unit after calling the calculate symbol context. If the compile unit is NULL, then we report an error via the module/debugger as this indicates an entry in the line table fails to resolve back to any compile unit. If the compile unit is not NULL and it differs from the current compile unit, we restore the current compile unit and line entry to ensure the call to .CalculateSymbolContext doesn't match something completely different, as can easily happen if LTO or other link time optimizations are enabled that could end up outlining or merging functions.
This patch allows breakpoint succeeding to work as expected and not get short circuited by our address lookup logic failing.
