* x86 asm reader: Don't copy operand size to instruction size for MOVSS and VMOVSS, because it is different for source and destination. Fixes breakage caused by fixing memory size of those instructions (Mantis #29954 and Mantis #29957).
+ Tests are extended to check that both OPR_LOCAL and OPR_REF memory operands compile without warnings as source and destination, in both Intel and AT&T syntax.
