Philippe Mathieu-Daudé 9d00539239 target/mips: Introduce decodetree structure for NEC Vr54xx extension
The decoder is called but doesn't decode anything. This will
ease reviewing the next commit.

Philippe Mathieu-Daudé 12f79f1173 target/mips: Merge 32-bit/64-bit Release6 decodetree definitions
We don't need to maintain 2 sets of decodetree definitions.
Merge them into a single file.

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.

Philippe Mathieu-Daudé ad520a9784 target/mips: Move sysemu TCG-specific code to tcg/sysemu/ subfolder
Move cp0_helper.c and mips-semi.c to the new tcg/sysemu/ folder,
adapting the Meson machinery.

Move the opcode definitions to tcg/sysemu_helper.h.inc.

Philippe Mathieu-Daudé 0a31c16c9c target/mips: Add simple user-mode mips_cpu_do_interrupt()
The #ifdef'ry hides that the user-mode implementation of
mips_cpu_do_interrupt() simply sets exception_index = EXCP_NONE.

Add this simple implementation to tcg/user/tlb_helper.c, and
the corresponding Meson machinery to build this file when user
emulation is configured.
