This is part of fixing the instruction predicates for MIPS.

Instructions affected:
mthc1, mfhc1, add.d, sub.d, mul.d, div.d,
mov.d, neg.d, cvt.w.d, cvt.d.s, cvt.d.w, cvt.s.d
These instructions are now defined for
microMIPS32r3 + microMIPS32r6 in MicroMipsInstrFPU.td
since they shared their encoding with those already defined
in microMIPS32r6InstrInfo.td and have been therefore
removed from the latter file.
Some instructions present in MicroMipsInstrFPU.td which
did not have both AFGR64 and FGR64 variants defined have
been altered to do so.

- Alter abs for micromips to have both AFGR64 and FGR64
variants, same as sqrt
- Remove sqrt and abs from MicroMips32r6InstrInfo.td,
use micromips FGR64 variants
- Restrict non-micromips abs/sqrt with NotInMicroMips

This patch resubmits the SVE ZIP1/ZIP2 patch series consisting of
of r320992, r320986, r320973, and r320970 by reverting
https://reviews.llvm.org/rL321024.
The issue that caused r321024 has been addressed in https://reviews.llvm.org/rL321158,
so this patch-series should be safe to resubmit.
llvm-svn: 321163
This reverts changes r320992, r320986, r320973, and r320970.
r320970 by itself breaks the test case, and the rest depend on it.
Test case will land soon.

Summary:
When emitting a diagnostic for an invalid operand, a specific diagnostic
should only be reported when the instruction being matched is actually
enabled by the feature flags.
Patch [3/4] in a series to add parsing of predicates and properly parse SVE
ZIP1/ZIP2 instructions. This patch fixes bogus diagnostic messages for when
the SVE feature is not specified.

Previously, the 'movep' instruction was defined for microMIPS32r3 and
shared that definition with microMIPS32R6. 'movep' was re-encoded for
microMIPS32r6, so this patch provides the correct encoding.
Secondly, correct the encoding of the 'rs' and 'rt' operands which have
an instruction specific encoding for the registers those operands accept.
Finally, correct the decoding of the 'dst_regs' operand which was extracting
the relevant field from the instruction, but was actually extracting the
field from the alreadly extracted field.

This patch adds the single operand form of the not alias to microMIPS and
MIPS along with additional tests.
This partially resolves PR/30381.
Thanks to Sean Bruno for reporting the issue!

For compatiblity with binutils, define these instructions to take
two registers with a 16bit unsigned immediate. Both of the registers
have to be same for dahi and dati.

Add the instruction alias sgtu (register form only), two operand forms of
s[rl]l and sra, and missing single/two operand forms of dnegu/neg.

Summary:
The bug was that microMIPS's [ls]w[lr]e instructions claimed to support a
12-bit offset when it is only 9-bit.
