Commit Message

Philippe Mathieu-Daudé Oct. 24, 2024, 7:54 p.m. UTC 
Similarly to commit 17c2c320f3c ("Introduce ase_mt_available helper"),
introduce the disas_mt_available() one which takes a DisasContext
argument to determine whether Multi-Threading is available by
checking the MT bit of the CP0_Config3 register.

Remove the then unused ASE_MT definition.

BTW I considered inlining it in translate.c but the MT code will
eventually be converted to decodetree so better keep this helper
in the translate.h header.
