ART: Generalize code to find PC for artInvokeInterfaceTrampoline
This allows to determine target method when the interface method has
no dex index, now also for X86-64 and ARM64.
Add constexpr functions to callee_save_frame.h to have compile-time
sizes of callee-save frames. Add a test that ensures they agree
with computations by the corresponding ArtMethod methods.
Move some instruction-set functions into the header file to allow
inlining them. Move arch-specific pointer sizes and alignment sizes
out of globals.h to instruction_set.h to reduce dependencies.
