[Patch, AArch64, Testsuite] Check for movi vectorization.

[Tejas Belagod]

Hi,

This change
+2014-12-05 Martin Jambor <mjam...@suse.cz>

+ PR ipa/64192
+ * ipa-prop.c (ipa_compute_jump_functions_for_edge): Convert alignment
+ from bits to bytes after checking they are byte-aligned.
+

causes AArch64's vect cost model to vectorize the loops in the 
gcc.target/aarch64/vect-movi.c with a different vectorization factor.

While I'm still trying to understand how this change affects 
vectorization, here is a patch to make the test more robust by improving 
regexp to make it check for either vectorization factor.

Tested vect-movi.c on aarch64-none-elf. OK for trunk?

Thanks,
Tejas.
