Hi,

This patch changes GAS to allow more system registers to be specified
using S3_<op1>_<Cn>_<Cm>_<op2>.  This relaxation enables the assembler
to accept more system registers without the need to add/maintain more
tables of system registers with specific names.

The disassembler has already been able to display these registers in the
same form.

OK for the trunk?

Thanks,
Yufeng
