Make APInt negate just do a 2's complement negate instead of subtract. NFC.
This is part of an effort to shave allocations from APInt heavy paths. I'll
be moving many of the other operators to r-value references soon and this is
a step towards doing that without too much duplication.
Saves 15k allocations when doing 'opt -O2 verify-uselistorder.bc'.
