mips32: Fix typo.

Fix some typo error and some errors in tests that was discovered while running Valgrind on MIPS/Android.
In some cases initial FCSR value wasn't being set properly.

Minor tweak in the vgdb instructions output by valgrind:
to make copy/paste and then editing the command easier,
put the --pid=3393 at the end of the instruction output by valgrind.

So, in gdb command history, one can just recuperate the previous target
command in the history and more easily change the pid.
I.e. have:

target remote | /home/philippe/valgrind/refactor_vgdb/Inst/lib/valgrind/../../bin/vgdb --vgdb-prefix=truc --pid=3393

instead of

target remote | /home/philippe/valgrind/refactor_vgdb/Inst/lib/valgrind/../../bin/vgdb --pid=3393 --vgdb-prefix=truc
