[tree-ssa] New regressions in branch

[Diego Novillo]

While talking with Jeff Law today, I realized that I didn't
mention the new failures on the branch after the merge.

	 FAIL: gcc.dg/i386-cadd.c scan-assembler sbb
	 FAIL: gcc.dg/uninit-C.c (test for excess errors)

I still haven't looked at either of them, but the second one is
due to a new test added to mainline.  The i386-cadd.c regression
is new.  I'm still not sure if it's also present in mainline or
if it's something in the branch.

	 FAIL: g++.dg/parse/qualified1.C (test for excess errors)

This is a new test brought in by the merge.  Again, I'm still not
sure if this fails in mainline or not.
