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.

Final patch that completes old JIT support for Mips:
...
-Fix binary codes and rename operands in .td files so that automatically
generated function MipsCodeEmitter::getBinaryCodeForInstr gives correct
encoding for instructions.
-Define new class FMem for instructions that access memory.
-Define new class FFRGPR for instructions that move data between GPR and
FPU general and control registers.
-Define custom encoder methods for memory operands, and also for size
operands of ext and ins instructions.
-Only static relocation model is currently implemented.

Fix handling of double precision loads and stores when Mips1 is targeted.
...
Mips1 does not support double precision loads or stores, therefore two single
precision loads or stores must be used in place of these instructions. This
patch treats double precision loads and stores as if they are legal
instructions until MCInstLowering, instead of generating the single precision
instructions during instruction selection or Prolog/Epilog code insertion.
Without the changes made in this patch, llc produces code that has the same
problem described in r137484 or bails out when
MipsInstrInfo::storeRegToStackSlot or loadRegFromStackSlot is called before
register allocation.
