Generate P/Invoke transitions for CoreRT.
This change adds support for CoreRT-style P/Invoke transitions
to RyuJIT. Instead of the usual inlined transition code, these
transitions are made up of calls to two new JIT helpers:
PInvokeTransitionFrame frame; // opaque local
CORINFO_HELP_INIT_PINVOKE_FRAME(&frame);
...
CORINFO_HELP_JIT_PINVOKE_BEGIN(&frame);
target(...);
CORINFO_HELP_JIT_PINVOKE_END(&frame);
...
The preemptive mode constraints apply between calls to
JIT_PINVOKE_BEGIN and JIT_PINVOKE_END: no managed references
may be live only in registers and managed references may not
be manipulated.
