While this patch is similar in spirit to V11 #15, I lost that patch, and I
re-implemented the check. Can I check this test into the trunk?

* gcc.target/powerpc/vec-extract-large-si.c: New test for
vec_extract from a vector unsigned int in memory with a large
offset.
* gcc.target/powerpc/vec-extract-large-di.c: New test for
vec_extract from a vector long in memory with a large offset.
* gcc.target/powerpc/vec-extract-large-sf.c: New test for
vec_extract from a vector float in memory with a large offset.
* gcc.target/powerpc/vec-extract-large-df.c: New test for
vec_extract from a vector double in memory with a large offset.
