[MIPS] Use mfhc1 and mthc1 to fix assembler error
https://bugs.webkit.org/show_bug.cgi?id=185464
Patch by Dominik Infuehr <[email protected]> on 2018-05-09
Reviewed by Yusuke Suzuki.
The binutils-assembler started to report failures for copying words between
GP and FP registers for odd FP register indices. Use mfhc1 and mthc1 instead
of mfc1 and mtc1 for conversion.
