Introduce two new setcond opcode variants which produce -1 instead
of 1 when the condition. For most of our hosts, producing -1 is
just as easy as 1, and avoid requiring a separate negate instruction.
Use the new opcode in tcg/tcg-op-gvec.c for integral expansion of
generic vector operations. I looked through target/ for obvious
pairings of setcond and neg.
