Implement most RyuJIT intrinsics

- Add lookup of all RyuJIT intrinsics
- Update manage implementations of the intrinsics to fit with what RyuJIT is capable of
- Make intrinsic expansions by the codegen to be optional by providing fallback paths
- Fix USE_PORTABLE_HELPERS to be defined for portable runtime only

These changes are under CORERT ifdefs as necessary to be reconciled with .NET Native for UWP later.
