Huh. OK, so we do some pointless vectorization (the store is in a BB
ending in __builtin_unreachable()) but the actual issue must be the
live lane extraction into the not vectorized scalar code:

GIMPLE testcase for the vectorization (w/o driver part). If you make the
condition non-uniform then we include the _28 SLP def in the SLP and
everything goes correct. So it might be that we need to special

Hmm, OK, so besides the incomplete bool pattern matching the issue seems to be
that while we reject the problematic conversion in vectorizable_conversion it
slips through via vectorizable_assignment because
