[PATCH] rs6000: Builtin test changes for int_128bit-runnable.c

Hi!  This patch is broken out from the test case patch for the new builtins support. The old builtins code performs gimple folding on 128-bit compares. This results in correct but very inefficient code. (I suspect we may be missing some optab entries, misleading gimple into 64-bit emulation.)
