Use a memcpy so that type based alias analysis sees the change.
The other option would be to do something like
if (that.isSingleWord())
VAL = that.VAL;
else
pVal = that.pVal
This bug was causing 86TTI::getIntImmCost to be miscompiled in a LTO
bootstrap in stage2, causing the build of stage3 to fail.
LLVM is getting quiet good at exploiting this. Not sure if there is anything
a sanitizer could do to help
