[llvm] [llvm] add missing #include of Compiler.h (PR #141780)

[Andrew Rogers via llvm-commits]

https://github.com/andrurogerz created https://github.com/llvm/llvm-project/pull/141780

Fixes a build break introduced in #136623. There were two files updated to reference the `LLVM_ABI` macro that were not updated to `#include "llvm/Support/Compiler.h"`

Failing build: https://green.lab.llvm.org/job/llvm.org/job/clang-stage2-Rthinlto/794/consoleFull#-471199310f80d942a-f672-4696-b0d9-c66cae8aa9dd
