Original PR under review: llvm/llvm-project#136114

As the commit introduced by #535 has resulted in a faulty C++ compiler which could not see system-provided standard C++ library, an alternative solution is now being cherry-picked here which appears to work with Amazon Linux 2023.

This is an one off change for the ATfL21 release.

Downstream issue: #533

…triple and handle RuntimeLibcalls #136114

This parses the "aarch64-amazon-linux" triple and updates
RuntimeLibcalls to mark the sincos* functions as available on Amazon
Linux. This allows these functions to be vectorized on Amazon Linux.
