03afdc28b3 target/mips: Implement Loongson CSR instructions 
Loongson introduced CSR instructions since 3A4000, which looks
similar to IOCSR and CPUCFG instructions we seen in LoongArch.

Unfortunately we don't have much document about those instructions,
bit fields of CPUCFG instructions and IOCSR registers can be found
at 3A4000's user manual, while instruction encodings can be found
at arch/mips/include/asm/mach-loongson64/loongson_regs.h from
Linux Kernel.

Our predefined CPUCFG bits are differ from actual 3A4000, since
we can't emulate all CPUCFG features present in 3A4000 for now,
we just enable bits for what we have in TCG.

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.

ecdbcb0a94 target/mips: Move helper_cache() to tcg/sysemu/special_helper.c 
Move helper_cache() to tcg/sysemu/special_helper.c.

The CACHE opcode is privileged and is not accessible in user
emulation. However we get a link failure when restricting the
symbol to sysemu. For now, add a stub helper to satisfy linking,
which abort if ever called.

Move the Special opcodes helpers to tcg/sysemu/special_helper.c.

Since mips_io_recompile_replay_branch() is set as

82ba42666c target/mips: only build mips-semi for softmmu 
The is_uhi gates all semihosting calls and always returns false for
CONFIG_USER_ONLY builds. There is no reason to build and link
mips-semi for these builds so lets fix that.

c1c9a10fb1 target/mips: Refactor and fix INSERT.<B|H|W|D> instructions 
The old version of the helper for the INSERT.<B|H|W|D> MSA instructions
has been replaced with four helpers that don't use switch, and change
the endianness of the given index, when executed on a big endian host.
