I had one local hack and just found it can survive on x86 bootstrapping and
regression testing. I guess maybe it's good to post here. Just ignore this if
it looks like noise. :) The point is to do the

bool patterns are to distinguish flag uses from data uses since a vectorized
flag true will be -1 while the unvectorized flag is 1 but of course any
data uses have to be retained. What we are missing here

IR in the bool case:
_1 = pb[i_13];
iftmp.0_7 = a[i_13];
iftmp.0_6 = b[i_13];
iftmp.0_3 = _1 ? iftmp.0_7 : iftmp.0_6;
c[i_13] = iftmp.0_3;
IR in the char case:
_1 = pc[i_13];
iftmp.1_7 =
