IRtranslator now translates bfloat. Switch tablegen to use extendedLLTs.
Around 300 regression tests fail to inst-select because GIM_SwitchType
does not accept LLT::scalar. Around 100 mir inst select tests had input
updated to i32/f32 and select successfully. Then there are 24 various
crashes, mostly combiner or machine-verifier, those tests are disabled.
Most problems come from mixing s32 with i32/f32 and the way operator==
works with extendedLLTs compared to GIM_SwitchType.
In general, for inst-select fixes, I think it would be best to avoid
explicit use of LLT::scalar in lowering to avoid mixing it with
LLT::integer/LLT::float See inst-select-extendedLLTs.mir and
inst-select-extendedLLTs-err.mir.
