When the allocator rewrite a spill register with new virtual register, it replaces other operands of the same register. Watch out for situations where
only some of the operands are sub-register uses.

type of SV has changed from what it originally was.
However we need the store width of the original.

If a value is incoming from outside the loop then the value does not need remapping and the value is never tracked through  LastValueMap.

should only effect x86 when using long double.  Now
12/16 bytes are output for long double globals (the
exact amount depends on the alignment).  This brings
globals in line with the rest of LLVM: the space
reserved for an object is now always the ABI size.
One tricky point is that only 10 bytes should be
output for long double if it is a field in a packed
struct, which is the reason for the additional
argument to EmitGlobalConstant.
