This patch adds a predicate to existing mips32 and mips64 so that those
instruction encodings can be excluded during mips16 processing.
This revision fixes the issue raised by Jim Grosbach.
bool hasStandardEncoding() const { return !inMips16Mode(); }
When micromips is added it will be
bool StandardEncoding() const { return !inMips16Mode()&& !inMicroMipsMode(); }
No additional testing is needed other than to assure that there is no regression
from this patch.
Patch by Reed Kotler.
