[PATCH] [PATCH][mips] Add range checks and transformation to octeon instructions in AsmParser.

[Kai Nacke]

Hi dsanders,

Hi Daniel!

This patch adds range checks to the immediate operands of octeon
instructions in the AsmParser. Like gas, it applies the following
transformations if the immediate is to large:

bbit0 $8, 42, foo => bbit032 $8, 10, foo
bbit1 $8, 46, foo => bbit132 $8, 14, foo
cins $8, $31, 32, 31 => cins32 $8, $31, 0, 31
exts $7, $4, 54, 9 => exts32 $7, $4, 22, 9

Please review.

Regards,
Kai
