-
-Fix s390x build broken by incorrect specification of the msgfi instruction used in MUL_IMM type operations. The instruction had been encoded as its 32-bit counterpart (msfi).
-
-In addition, the s390x microcode makes the mono_strength_reduction_division unnecessary so this can be bypassed.
-
-The change to basic.make is just to avoid error messages when basic-profile-check.exe hasn't been built yet.
