Add support for emulating:
- S32LDDV and S32LDDVR
- S32STD and S32STDR
- S32STDV and S32STDVR
MXU instructions.
Add support for emulating MXU instructions with address register
post-modify counterparts:
- S32LDI and S32LDIR
- S32LDIV and S32LDIVR
- S32SDI and S32SDIR
- S32SDIV and S32SDIVR
Refactor support for emulating the S32LDD and S32LDDR instructions.

Move most includes from *translate*.c to translate.h, ensuring
that we get the ordering correct. Ensure cpu.h is first.
Use disas/disas.h instead of exec/log.h.
Drop otherwise unused includes.

Memory operations that are not already aligned, or otherwise

There were two bugs here: (1) the required endianness was
not present in the MemOp, and (2) we were not providing a
zero-extended input to the bswap as semantics required.
The best fix is to fold the bswap into the memory operation,
producing the desired result directly.

Implement the new semantics in the fallback expansion.
Change all callers to supply the flags that keep the
semantics unchanged locally.

Since all entries are no more than 3/4/6 bytes (including nul
terminator), can save space and pie runtime relocations by
declaring regnames[] as array of 3/4/6 const char.

To ease maintenance, move all TCG specific files under the tcg/
sub-directory. Adapt the Meson machinery.
The following prototypes:
- mips_tcg_init()
- mips_cpu_do_unaligned_access()
- mips_cpu_do_transaction_failed()
can now be restricted to the "tcg-internal.h" header.
