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

[iklam]

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.

Tested with mach5: tier1, builds-tier2, builds-tier3, builds-tier4 and builds-tier5 on mach5, plus locally building arm, aarch64, s390, ppc64, and zero.
