  [DirectX] Add isinf f16 emulation for SM6.8 and lower (#156932)

fixes #156068

- We needed to add a new sub arch to the target tripple so we can test
that emulation does not happen when targeting SM6.9
- The HLSL toolchain needed to be updated to handle the conversion of
strings to enums for the new sub arch.
- The emulation is done in DXILIntrinsicExpansion.cpp and needs to be
able to convert both llvm.is.fpclass and lvm.dx.isinf to the proper
emulation
- test updates in TargetParser/TripleTest.cpp, isinf.ll, is_fpclass.ll,
and DXCModeTest.cpp

  Revert "[clang][dataflow] Transfer more cast expressions." (#157148)

Reverts llvm/llvm-project#153066

copyRecord crashes if copying from the RecordStorageLocation shared by
the base/derived objects after a DerivedToBase cast because the source
type is still `Derived` but the copy destination could be of a sibling
type derived from Base that has children not present in `Derived`.

For example, running the dataflow analysis over the following produces
UB by nullptr deref, or fails asserts if enabled:

```cc
struct Base {};

struct DerivedOne : public Base {
  int DerivedOneField;
};

struct DerivedTwo : public Base {
  int DerivedTwoField;

  DerivedTwo(const DerivedOne& d1)
      : Base(d1), DerivedTwoField(d1.DerivedOneField) {}
};
```

The constructor initializer for `DerivedTwoField` serves the purpose of
forcing `DerivedOneField` to be modeled, which is necessary to trigger
the crash but not the assert failure.

…ilation database

Currently a hard crash encourages people to report a bug upstream, but
this is not really a bug. Instead, print an error and use a reasonable
default (the current working directory).

Fixes #57264

The getPageSize() function is defined in the platform-specific
source files but used in common.cpp.  Every function used across
files should be declared in a header so the same declaration is
in scope for the callers and the definition.

  [RISCV] Add th.ext(u) to RISCVDAGToDAGISel::hasAllNBitUsers. (#157133)

These instructions are being used by the scalar efficiency SIG to
determine if we should have a standard instruction. Improving our
support for these instructions may give better data for their analysis.

I'll follow up by adding this to RISCVOptWInstrs too which will remove
the 'w' suffixes added here.

These instructions extract and range of bits, move them to the LSB
then sign or zero extend the result to fill the upper bits. If
the extracted bits is small enough then the result will have 33
sign bits.

  [OpenACC][NFCI] Split recipe generation into its own class (#157160)

The recipe generation was dependent on the clause kind, which meant we
had all of the recipe generation duplicated in each of clauses. This
patch copy/pastes all of them into their own type to do recipe
generation, which should reduce clang's size.

Additionally, we've moved it off into its own file, which should make
readability/organization improvements.

  [LLD][COFF] Add more `--time-trace` tags for ThinLTO linking (#156471)

In order to better see what's going on during ThinLTO linking, this PR
adds more profile tags when using `--time-trace` on a `lld-link.exe`
invocation.

After PR, linking `clang.exe`:

Linking a custom (Unreal Engine game) binary gives a completly
different picture, probably because of using Unity files, and the sheer
amount of input files (here, providing over 60 GB of .OBJs/.LIBs).
