CodeGen: enable mov.w/mov.t pairs with minsize for WoA
Windows on ARM uses COFF/PE which is intrinsically position independent. For
the case of 32-bit immediates, use a pair-wise relocation as otherwise we may
exceed the range of operators. This fixes a code generation crash when using
-Oz when targeting Windows on ARM.
