Hmm, but according to
http://itanium-cxx-abi.github.io/cxx-abi/abi.html#mangling.literal the mangling
of a negative integer literal is prefixed with "n", and according to
http://itanium-cxx-abi.github.io/cxx-abi/abi.html#mangle.operator-name the
mangling of -<expr> is prefixed with "ng". So I don't see why -1 and -(1)
should be given the same mangling. ISTM GCC is already getting the mangling
right.
