This fixes the ICE with -m32 -mpowerpc64 on many of the testcases that
use atomics:

gcc:
-# of expected passes           108465
-# of unexpected failures       365
+# of expected passes           108499
+# of unexpected failures       303

libgomp:
-# of expected passes           8664
-# of unexpected failures       126
-# of unresolved testcases      63
+# of expected passes           8790

Not bad for a one-liner :-)

Bootstrapped and tested on powerpc64-linux, -m64,-m32,-m32/-mpowerpc64;
no new failures, and the above improvements.

Okay to apply?
