Make BOLT as stable feature

[corona10]

Using a BOLT still not guarantee the unexpected behavior changes.
For example, I observed that #53093 is raised if the binary is optimized by BOLT.
We can reduce several too aggressive optimization.

• Optimizing BOLT flags #128514
• Choose the APIs that should not be optimized BOLT (e.g -skip-funcs)
• Update libregrtest.utils.get_build_info()
• Update make test to work correctly (Should skip the BOLT phase if the binary is already BOLTed)
• Define minimum LLVM version
• Enhance the BOLT build process #101282
• Test BOLT builds in CI #128515

I am analyzing several effects of BOLT.

Need to update get_build_info for the BOLT binary.
