  1. These changes enable the inlining of some PInvokes that do not requir… 

    …e any marshalling. With inlined pinvokes, R2R performance should become slightly better, since we'll avoid jitting some of the pinvoke IL stubs that we jit today for S.P.CoreLib. Performance gains not yet measured.

Added JIT_PInvokeBegin/End helpers for all architectures. Linux stubs not yet implemented
Add INLINE_GETTHREAD for arm/arm64
Set CORJIT_FLAG_USE_PINVOKE_HELPERS jit flag for ReadyToRun compilations
