[PATCH] V12 patch #14 of 14, Add tests for generating prefixed instructions when using vec_extract with large offsets with -mcpu=future

[Michael Meissner <meissner at linux dot ibm dot com>]

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.
