936dca0e2d Constify backends (#1549)
* Constify registerinfo.py output

Remove two conditionals separating identical bits of code.
Add "const" markup to MCRegisterDesc and MCRegisterClass.

Signed-off-by: Richard Henderson <rth@twiddle.net>

* Constify instrinfo-arch.py output

In this case, do not actively strip const.

* Constify the Mips backend

The Mips backend has not been regenerated from LLVM recently,
and there are more fixups required than I'd like.  Just apply
the fixes to the tables by hand for now.

The mapping of system register to indexes is easy to
generate read-only.  Since we know the indexes are
between 0 and 31, use uint8_t instead of unsigned.
