MIPS: math-emu: Add mfhc1 & mthc1 support.
This patch adds support for the mfhc1 & mthc1 instructions to the FPU
emulator. These instructions were introduced in release 2 of the MIPS32
& MIPS64 architectures and allow access to the most significant 32 bits
of a 64-bit FP register.
[ralf@linux-mips.org: Fix ifdef hell added by original patch.]
