Daniel Sanders 1f6f0f4b54 [mips] Use MTHC1 when it is available (MIPS32r2 and later) for both FP32 and FP64
Summary:
To make this work for both AFGR64 and FGR64 register sets, I've had to make the
instruction definition consistent with the white lie (that it reads the lower
32-bits of the register) when they are generated by expandBuildPairF64().

Corrected the definition of hasMips32r2() and hasMips64r2() to include
MIPS32r6 and MIPS64r6.

Depends on D3956

Daniel Sanders 863c35a358 [mips] Fix fcopysign for MIPS-IV and add the test.
Summary:
This was another incorrect use of hasMips64() vs isGP64bit().

Akira Hatanaka 4f5c8421b3 Fix bugs in lowering of FCOPYSIGN nodes.
- FCOPYSIGN nodes that have operands of different types were not handled.
- Different code was generated depending on the endianness of the target.

Additionally, code is added that emits INS and EXT instructions, if they are
supported by target (they are R2 instructions).

Akira Hatanaka db47e0c49d Add patterns for matching immediates whose lower 16-bit is cleared. These
patterns emit a single LUi instruction instead of a pair of LUi and ORi.
