Revert r109652, and remove the offending assert in loadRegFromStackSlot instead.
We do sometimes load from a too small stack slot when dealing with x86 arguments
(varargs and smaller-than-32-bit args). It looks like we know what we are doing
in those cases, so I am going to remove the assert instead of artifically
enlarging stack slot sizes.
The assert in storeRegToStackSlot stays in. We don't want to write beyond the
bounds of a stack slot.
