[Bug bootstrap/21335] bootstrap fails with CFLAGS="-O3 -ftree-vectorize"

["dorit at il dot ibm dot com" <gcc-bugzilla@gcc.gnu.org>]

I get the following bootstrap failure on powerpc-apple-darwin, with "-O2 -ftree-
vectorize":

../../gcc/gcc/builtins.c: In function 'fold_builtin_1':
../../gcc/gcc/builtins.c:8451: internal compiler error: Bus error

which seems to happen during tree-if-conversion:
