[PATCH v3 03/32] tests/tcg/mips: Run MSA opcodes tests on user-mode emulation

[Philippe Mathieu-Daudé]

The following commits added various user-mode tests
for various MSA instructions:

 - 0fdd986a6c8 ("Add tests for MSA integer add instructions")
 - 1be82d89011 ("Add tests for MSA integer average instructions")
 - 1d336c87a3c ("Add tests for MSA bit set instructions")
 - 1e6bea794c8 ("Add tests for MSA integer max/min instructions")
 - 2a367db039f ("Add tests for MSA pack instructions")
 - 3d9569b8550 ("Add tests for MSA move instructions")
 - 4b302ce90db ("Add tests for MSA integer multiply instructions")
 - 520e210c0aa ("Add tests for MSA integer compare instructions")
 - 53e116fed6d ("Add tests for MSA integer subtract instructions")
 - 666952ea7c1 ("Add tests for MSA bit move instructions")
 - 72f463bc080 ("Add tests for MSA integer divide instructions")
 - 8598f5fac1c ("Add tests for MSA FP max/min instructions")
 - 99d423e576a ("Add tests for MSA shift instructions")
 - a8f91dd9fd0 ("Add tests for MSA integer dot product instructions")
 - b62592ab655 ("Add tests for MSA bit counting instructions")
 - ba632924450 ("Add tests for MSA logic instructions")
 - fc76f486677 ("Add tests for MSA interleave instructions")

Cover them in the buildsys machinery so they are run automatically
when calling 'make check-tcg'.

Start running them on the mips64el target.

Notes:

- I am using $wilcard because because the test files are in multiple
directories ($MSA_TEST_CLASS).

- mips32 tests are disabled because the Debian toolchain produces:

  /usr/mips-linux-gnu/include/gnu/stubs.h:17:11: fatal error:
  gnu/stubs-o32_hard_2008.h: No such file or directory
   # include <gnu/stubs-o32_hard_2008.h>
             ^~~~~~~~~~~~~~~~~~~~~~~~~~~
