SWM32 should store a sequence of 32-bit words from the GPRs, but it was
incorrectly coded to store 16-bit words only. As a result, an LWM32 that
usually follows would restore invalid register values.
Fixes: 7dd547e5ab ("target/mips: Use cpu_*_mmuidx_ra instead of
MMU_MODE*_SUFFIX")

The target endianess information is stored in the BigEndian
bit of the Config0 register in CP0.
Replace the GET_LMASK() macro by an inlined get_lmask() function,
passing CPUMIPSState and the word size as argument.
We can remove another use of the TARGET_WORDS_BIGENDIAN definition.

The target endianess information is stored in the BigEndian
bit of the Config0 register in CP0.
As a first step, inline the GET_OFFSET() macro, calling
cpu_is_bigendian() to get the 'direction' of the offset.

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.
