Fangrui Song 63fbc77121 [Driver][test] Remove unused/obsoleted REQUIRES: clang-driver 
It (introduced by 556d713c70) appears to be
related to the removed dragonegg project. In addition, the feature was a bit
misnamed and may lur users to unnecessarily use it.

Sameer Sahasrabuddhe ed181efa17 [HIP][AMDGPU] expand printf when compiling HIP to AMDGPU 
Summary:
This change implements the expansion in two parts:
- Add a utility function emitAMDGPUPrintfCall() in LLVM.
- Invoke the above function from Clang CodeGen, when processing a HIP
  program for the AMDGPU target.

The printf expansion has undefined behaviour if the format string is
not a compile-time constant. As a sufficient condition, the HIP
ToolChain now emits -Werror=format-nonliteral.
