8ef3915263 disas/mips: disable unused mips16_to_32_reg_map[]
This array is used by print_mips16_insn_arg() which is guarded by #if 0.
Therefore doing the same with the array as it generates clang warnings.

9456c2fbcd target-mips: add TLBINV support
For Standard TLB configuration (Config.MT=1):

TLBINV invalidates a set of TLB entries based on ASID. The virtual address is
ignored in the entry match. TLB entries which have their G bit set to 1 are not
modified.

TLBINVF causes all entries to be invalidated.

Single TLB entry can be marked as invalid on TLB entry write by having
EntryHi.EHINV set to 1.

e7f16abbc5 target-mips: add new Floating Point instructions
In terms of encoding MIPS32R6 MIN.fmt, MAX.fmt, MINA.fmt, MAXA.fmt replaced
MIPS-3D RECIP1, RECIP2, RSQRT1, RSQRT2 instructions.

In R6 all Floating Point instructions are supposed to be IEEE-2008 compliant
i.e. FIR.HAS2008 always 1. However, QEMU softfloat for MIPS has not been
updated yet.

31837be3ee target-mips: add compact and CP1 branches
Introduce MIPS32R6 Compact Branch instructions which do not have delay slot -
they have forbidden slot instead. However, current implementation does not
support forbidden slot yet.

Add also BC1EQZ and BC1NEZ instructions.
