Two i386 test cases, bmi2-mulx-highpart-1.c and mulq-highpart.c, have been updated to include the -mtune=generic flag. This is necessary because the expected instruction order in these tests relies on the generic tuning, which can be disrupted by more specific tunings like -march=cascadelake that reorder instructions.
