matched.
This simplifies selection of floating point loads/stores.
No functionality change intended.

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.

FFR1_W_M and FFR1P_M. The new instruction definitions have one-to-one
correspondence with the instructions in the ISA manual.

use load/store fragments defined in TargetSelectionDAG.td in place of them.
Unaligned loads/stores are either expanded or lowered to target-specific nodes,
so instruction selection should see only aligned load/store nodes.
No changes in functionality.

PseudoSE (mips32/64 pseudo) classes.

single-precision load and store.
Also avoid selecting LUXC1 and SUXC1 instructions during isel. It is incorrect
to map unaligned floating point load/store nodes to these instructions.

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.

and stores was added.
- SelectAddr should return false if Parent is an unaligned f32 load or store.
- Only aligned load and store nodes should be matched to select reg+imm
floating point instructions.
- MIPS does not have support for f64 unaligned load or store instructions.

-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.
