(Except as mentioned, the XPASS issue does not apply to
h8300; it's "i16lp32".  It remains in the set of targets
that were tested though.)

Subject: [PATCH 2/2] testsuite: Fix XPASS for gcc.dg/tree-ssa/scev-3.c, -4.c and -5.c [PR112786]

This is the second alternative, slightly more trivial than the first.

Tested cris-elf, arm-eabi (default), x86_64-linux, ditto -m32,
h8300-elf and shle-linux; xpassing, skipped and passing as
applicable and intended.

Ok to commit?

Results differ between ARM sub-targets, thus better to skip these
tests.  They are known to fail only for ia32-elf.

	PR testsuite/112786
	* gcc.dg/tree-ssa/scev-3.c, gcc.dg/tree-ssa/scev-4.c,
	gcc.dg/tree-ssa/scev-5.c: Revert last change.  Instead, skip dump
	match for arm*.
