Richard Henderson 8cab4157e9 target/mips: Tidy helpers for translation
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.

Richard Henderson 0d5bede468 target/mips: Add missing default_tcg_memop_mask
Memory operations that are not already aligned, or otherwise
marked up, require addition of ctx->default_tcg_memop_mask.

Richard Henderson 92ecfab50e target/mips: Fix gen_mxu_s32ldd_s32lddr
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.

Richard Henderson 2b836c2ac1 tcg: Add flags argument to tcg_gen_bswap16_*, tcg_gen_bswap32_i64
Implement the new semantics in the fallback expansion.
Change all callers to supply the flags that keep the
semantics unchanged locally.

Philippe Mathieu-Daudé 0610677293 target/mips: Optimize regnames[] arrays
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.

Philippe Mathieu-Daudé a2b0a27d33 target/mips: Move TCG source files under tcg/ sub directory
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.
