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.

As pointed out by Maciej, POOL16C minor opcodes were mostly shifted
by one bit. Correct those opcodes, and also add jraddiusp to the enum.

Add structures for all the MIPS16e instructions. Also add the
enumerations for all the bit fields for opcodes, functions, etc.

Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.
