@cfallin A side question - I noticed that Bconst generates 1 for the true value instead of -1 (e.g. 0xFFFFFFFF for bconst.b32 true; same on x86), but then I remembered your changes in #2058. Is this the expected behaviour? And then the other question - what would be the correct value for the vector counterpart? Currently we generate a vector with 1s in every lane.

@cfallin A side note about possible future work - the scalar boolean handling could be improved by using the CSETM (instead of CSET) and SBFX/SBFM instructions.
