  [X86] Hygon Processors Initial enablement (#187622)

This patch adds initial support for several Hygon architectures.

The Hygon architectures include:

- c86-4g-m4
- c86-4g-m6
- c86-4g-m7

This patch includes:

- Added Hygon architectures CPU targets recognition in Clang and LLVM
- Added Hygon architectures to target parser and host CPU detection
- Updated compiler-rt CPU model detection for Hygon architectures
- Added Hygon architectures to various optimizer tests
- Added scheduler models for Hygon architectures CPU targets
