i386: Add -mtune=generic to highpart multiplication tests

The check-function-bodies patterns in bmi2-mulx-highpart-1.c and
mulq-highpart.c expect the instruction order produced with generic
tuning.  With -march=cascadelake the scheduler swaps the movl and
movabsq instructions, so pin -mtune=generic.

gcc/testsuite/ChangeLog:

	* gcc.target/i386/bmi2-mulx-highpart-1.c: Add -mtune=generic
	to dg-options.
	* gcc.target/i386/mulq-highpart.c: Likewise.
