[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)

[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.

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.

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.
