b597ec3e08 Opportunistically predict BLR destinations using RET. 
When executing a BL-type instruction, push the new LR onto the stack,
then CALL the dispatcher or linked block rather than JMPing to it.  When
executing BLR, compare [rsp+8] to LR, and RET if it's right, which it
usually will be unless the thread was switched out.  If it's not right,
reset RSP to avoid overflow.

This both saves a trip through the dispatcher and improves branch
prediction.

There is a small possibility of stack overflow anyway, which should
be handled... *yawn*

558dee84ca Wrap some function calls in ABI_Push|PopRegistersAndAdjustStack(0, 0); 
These calls are made outside of JIT blocks, and thus previously did not
read any protection - register use is taken into account and the outer
dispatcher stack frame is sufficient.  However, if data is to be stored
on the stack, these calls must reserve stack shadow space on Windows to
avoid clobbering it.

2a0b06f08c JIT: simpler fallback conditions for load/store float 
I wasn't really thinking when I wrote these; d/s are for float registers, not
gprs.

6956df79b2 Fix Fastmem in JitIL for massive speed gains. 
JitIL's fastmem was stubbed out when Sonicadvance1 merged JitARMIL
into the tree. Since JitARMIL has been deleted, I simply re-arrange
the inheritance to base JitIL on Jitx86Base, so it can inherit the
backpatch function.
