[libc++][memory_resource] Applied `[[nodiscard]]` (#172134)
`[[nodiscard]]` should be applied to functions where discarding the
return value is most likely a correctness issue.

[flang] Add traits to more AST nodes
Follow-up to PR175211.
There are still a few AST nodes that don't have any of the standard
traits (Wrapper/Tuple/etc). Because of that they require special
handling in the parse tree visitor.
Convert a subset of these nodes to the typical format, and remove the
special cases from the parse tree visitor.
The members of these nodes were frequently used, so instead of extracting
them by hand each time use helper member functions to access them.
ValueTracking: Fix handling of fadd with mixed denormal modes (#175454)
Fix case where the input mode is IEEE, the output flushes, and the
input could be subnormal. Also improves accuracy with positive zero
case.
[AMDGPU] Use -filetype=null for more MC tests. NFCI. (#175567)
Following on from #175543 which did the same only for tests not using
`FileCheck -implicit-check-not=error:` or similar.
[CMake][NFC] Don't use uninitialized LLVM_REQUIRES_* (#175554)
LLVM_REQUIRES_* are per-target flags that are never set globally. Yet,
some files used these (undefined) flags for some logic. This patch
emoves these dead checks/unconditionally executes the logic. Note that
the referenced *.exports files are empty, so there is no need to make
related logic conditional on MSVC.
[clang] Prevent sandbox violations in `CrossTranslationUnitContext` (#175097)
This uses the VFS to load a file instead of using
`MemoryBuffer::getBufferForFile()` directly to avoid sandbox violation.
Sandbox is then disabled for `CreateASTUnitFromCommandLine()` which
invokes the driver which is not expected to be free of sandbox
violations.
[clang] Bypass sandbox in `ModuleDependencyCollector` (#175220)
This PR disables the sandbox for file collection within
`ModuleDependencyCollector`. This is typically only invoked when the
`-module-dependency-dir` option is specified for generating a crash
report, where the sandbox is not as crucial as for regular compilation.
[SPIRV] Deduce result type for `G_SEXT` and `G_ZEXT` (#175401)
During legalisation we can fold / combine `sext` followed by a widening
via `zext`. Unfortunately, this yields a new result register with no
SPIRV Type, which leads to incorrect behaviour during post legalisation
when we end up deducing the (narrower) type from the operand. This patch
corrects the behaviour in that it ensures that we use the (widened) type
of the result to yield the SPIRV Type for the register.
[CMake][NFC] Drop unnecessary GTest RTTI define (#175555)
gtest automatically determines GTEST_HAS_RTTI from pre-defined compiler
macros, there is no need to explicitly define this and especially no
need to define this for every single source file.
[VPlan] Give VPInstruction::ExplicitVectorLength name. NFC (#175493)
This makes it a tad easier to read VPlan dumps, e.g.
WIDEN vp.store vp<%7>, ir<%val>, vp<%5>
->
WIDEN vp.store vp<%7>, ir<%val>, vp<%evl>

graphics/jogl: pin to java 8
After removing source="1.4" from build.xml it still errors on
classes that are removed from jdk11.

[AArch64] Add support for range prefetch intrinsic (#170490)
This patch adds support in Clang for the RPRFM instruction, by adding
the following intrinsics:
```
void __pldx_range(unsigned int *access_kind*, unsigned int retention_policy,
signed int length*, unsigned int count, signed int stride,
size_t reuse distance, void const *addr);
void __pld_range(unsigned int access_kind*, unsigned int retention_policy,
uint64_t metadata, void const *addr);
```
The `__ARM_PREFETCH_RANGE` macro can be used to test whether these
intrinsics are implemented. If the RPRFM instruction is not available, this
instruction is a NOP.
This implements the following ACLE proposal:

[CMake] Move RTTI flag calculation to AddLLVM.cmake (#175553)
This should help users who use AddLLVM.cmake without HandleLLVMOptions.
Note that remains MSVC is unlikely to work.
Follow up of #174084.
