01c85e60a4 meson: Rename target_softmmu_arch -> target_system_arch
Finish the convertion started with commit de6cd7599b
("meson: Replace softmmu_ss -> system_ss"). If the
$target_type is 'system', then use the target_system_arch[]
source set :)

Mechanical change doing:

  $ sed -i -e s/target_softmmu_arch/target_system_arch/g \
      $(git grep -l target_softmmu_arch)

de6cd7599b meson: Replace softmmu_ss -> system_ss
We use the user_ss[] array to hold the user emulation sources,
and the softmmu_ss[] array to hold the system emulation ones.
Hold the latter in the 'system_ss[]' array for parity with user
emulation.

Mechanical change doing:

  $ sed -i -e s/softmmu_ss/system_ss/g $(git grep -l softmmu_ss)

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.

0a31c16c9c target/mips: Add simple user-mode mips_cpu_do_interrupt()

mips_cpu_do_interrupt() simply sets exception_index = EXCP_NONE.

fed50ffd5c target/mips: Move msa_reset() to new source file
mips_cpu_reset() is used by all accelerators, and calls
msa_reset(), which is defined in msa_helper.c.

Beside msa_reset(), the rest of msa_helper.c is only useful
to the TCG accelerator. To be able to restrict this helper
file to TCG, we need to move msa_reset() out of it.

830a72301c target/mips: Move IEEE rounding mode array to new source file
restore_msa_fp_status() is declared inlined in fpu_helper.h,
and uses the ieee_rm[] array. Therefore any code calling
restore_msa_fp_status() must have access to this ieee_rm[] array.

kvm_mips_get_fpu_registers(), which is in target/mips/kvm.c,
calls restore_msa_fp_status.

Except this tiny array, the rest of fpu_helper.c is only useful
for the TCG accelerator.

To be able to restrict fpu_helper.c to TCG, we need to move the
ieee_rm[] array to a new source file.
