[clang-tools-extra] cea0eea - [llvm] Split out DenseMapInfo specialization

LOG: [llvm] Split out DenseMapInfo specialization
Remove the `DenseMapInfo>` variant out from
`llvm/ADT/DenseMapInfo.h` into a separate header
`llvm/ADT/DenseMapInfoVariant.h`
This allows us to remove the `` include, which is being
transitively and unncessary included in all translation units that
include `llvm/ADT/DenseMap.h`.
There have been similar changes to move out specializations for
* `APInt.h` fd7e309e02fd226b0390888388ed732608e52c73 and
* `StringRef.h`/`ArrayRef.h`
983565a6fe4a9f40c7caf82b65c650c20dbcc104
to reduce the compilation time. As we are unable to move the
specialization into ``, we create a separate
`DenseMapInfoVariant.h` header that can be used by anyone who needs this
specialization.
This reduces the total number of preprocessing tokens across the LLVM
source files in lib from (roughly) 1,964,876,961 to 1,936,551,496 - a
reduction of ~1.44%. This should result in a small improvement in
compilation time.

[clang] f0fa2d7 - [llvm] Move AttributeMask to a separate header

LOG: [llvm] Move AttributeMask to a separate header
Move `AttributeMask` out of `llvm/IR/Attributes.h` to a new file
`llvm/IR/AttributeMask.h`. After doing this we can remove the
`#include ` and `#include ` directives from `Attributes.h`.
Since there are many headers including `Attributes.h`, but not needing
the definition of `AttributeMask`, this causes unnecessary bloating of
the translation units and slows down compilation.
This commit adds in the include directive for `llvm/IR/AttributeMask.h`
to the handful of source files that need to see the definition.
This reduces the total number of preprocessing tokens across the LLVM
source files in lib from (roughly) 1,917,509,187 to 1,902,982,273 - a
reduction of ~0.76%. This should result in a small improvement in
compilation time.
