Fixed some unary operators

There were a few issues in unary operators:
- Many were not compiling because the promote function had not
  been adjusted to take the new builtin functions into account
- abs and sign had not been implemented for int
- For the integer abs version, used pabsd. Removed the extra
  argument, which seemed unnecessary (abs should have 1 input,
  1 output, AFAIK).
