For now they are all copied to binary directory, once the project is more mature
it can be stripped down.

Avoids that weird effect where scrolling offsets code from 4-byte boundaries,
showing nonsense 75% of the time.

9ab816e6e9 JIT: fix regression in ps_sel 
My code didn't maintain correct semantics with floating-point NaNs (a < b is
not the same as "not a >= b" in float), which seems to have broken FIFA 12.

755bd2c445 Reorganize backpatching a bit. Untested on ARM. 
Rather than *MemTools.cpp checking whether the address is in the
emulated range itself (which, as of the next commit, doesn't cover every
kind of access the JIT might want to intercept) and doing PC
replacement, they just pass the access address and context to
jit->HandleFault, which does the rest itself.

Because SContext is now in JitInterface, I wanted JitBackpatch.h (which
defines it) to be lightweight, so I moved TrampolineCache and associated
x64{Analyzer,Emitter} dependencies into its own file.  I hate adding new
files in three places, two of which are MSVC...

While I'm at it, edit a misleading comment.

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

gprs.
