[Patch, AArch64] Make <su>mull<q> target tests more robust.

Hi,

Attached is a patch that makes the test case for <su>mull<q> more robust by 
looking for {scan-assembler "smull v[0-9]+\.<type>}" where <type> = {8h,
4s, 2d} and "smull2 v[0-9]+\.<type>}" where <type> = {8h, 4s, 2d} instead of 
looking for a specific number of occurances of "smull v" which can vary with the 
vectorization factor.

Tested on aarch64-4.7-branch and trunk for aarch64-none-elf. OK to commit on 
aarch64-4.7-branch and trunk?

Thanks,
Tejas Belagod

	instructions generated instead of number of occurances.
