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.

cases.

Added detection of end-of-stream in deserializer.

in AsmParser, since its only use is for parameters.

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

pointer backpatching in deserializer were improperly created and
resulted in an assertion failure.
