Hi,

This patch adds some extra tests for the sve2p1 "addqv, andqv, smaxqv,
sminqv, umaxqv, uminqv, eorqv, faddqv, fmaxnmqv, fmaxqv, fminnmqv and
fminqv" instructions.

The patch also adds couple of negative testcases, sve2p1-1-bad.d testcase
without "+sve2p1" option and sve2p1-2-bad.d testcase with wrong operands
for sve2p1 instructions.

Regression testing for aarch64-none-elf target and found no regressions.

Ok for binutils-master?

Regards,
Srinath.
