a796d90c0e [mips] Use ptr_rc to simplify definitions of base+index load/store instructions.
Also, fix predicates.

3531db14c6 [mips] Define register class FGRH32 for the high half of the 64-bit floating

definitions for instructions mfhc1 and mthc1. Also, remove sub-register indices
sub_fpeven and sub_fpodd and use sub_lo and sub_hi instead.

a98a486ad1 [mips] Resolve register classes dynamically using ptr_rc to reduce the number of

definition.

ae7e7cb3d3 [mips] Improve instruction selection for pattern (store (fp_to_sint $src), $ptr).
Previously, three instructions were needed:

trunc.w.s $f0, $f2

Now we need only two:

trunc.w.s $f0, $f2
swc1 $f0, 0($2)

ec4db6ab5f [mips] Fix instruction selection pattern for sint_to_fp node to avoid emitting an
invalid instruction sequence.

Rather than emitting an int-to-FP move instruction and an int-to-FP conversion
instruction during instruction selection, we emit a pseudo instruction which gets
expanded post-RA. Without this change, register allocation can possibly insert a
floating point register move instruction between the two instructions, which is not
valid according to the ISA manual.

mtc1 $f4, $4         # int-to-fp move instruction.
mov.s $f2, $f4       # move contents of $f4 to $f2.
cvt.s.w $f0, $f2     # int-to-fp conversion.

ec3199f675 This patch tackles the problem of parsing Mips
register names in the standalone assembler llvm-mc.

Registers such as $A1 can represent either a 32 or
64 bit register based on the instruction using it.
In addition, based on the abi, $T0 can represent different
32 bit registers.


The problem is resolved by the Mips specific AsmParser 
td definitions changing to work together. Many cases of
RegisterClass parameters are now RegisterOperand.

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.

c3f16b316a 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.

614051a1c5 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.
