3. Added mayLoad and mayStore assignements for the load/store instructions added and for ones already there that did not have this assignment.
4. Another patch will deal with the problem of load/store byte/halfword to the stack. This is a particular Mips16 problem.

Add missing function CreateFPCast to the TargetFolder. It's there in the other

folders and not having it here fails to compile if you actually try to use it.
Also, CreatePointerCast was failing to do the part where it does TD-aware
constant folding. Granted there is exactly one case where that it will ever
do anything, but there's no reason to skip it. For reference, that case is a
subtraction between two constant offsets on the same global variable, eg.,
"&A[123] - &A[4].f".
