RFR: 8258074: Move some flags related to compiler to compiler_globals.hpp

[Ioi Lam]

Many flags in globals.hpp are related to the compiler, and are mostly used only by the compiler source files. These flags should be moved to compiler_globals.hpp

Examples:

- CompileCommandFile
- Tier2CompileThreshold
- HugeMethodLimit

This speeds up HotSpot build time, and improves modularity.

This RFE is the first step -- it moves a few dozen flags that are straight-forward to move. Other flags may be moved by follow-up RFEs.
