PTX: Fix predicate logic bug
Code such as:
%vreg100 = setcc %vreg10, -1, SETNE
brcond %vreg10, %tgt
was being incorrectly morphed into
%vreg100 = and %vreg10, 1
brcond %vreg10, %tgt
where the 'and' instruction could be eliminated since
such logic is on 1-bit types in the PTX back-end, leaving
us with just:
brcond %vreg10, %tgt
which essentially gives us inverted branch conditions.
