DEF_BUILTIN(NAME, N_ARGS, ID, TYPE, ICODE)
NAME: The name as visible by the user as a C string.
ID: An integer to identify the built-in.
N_ARGS: Number of input arguments. If special treatment is needed,
set to -1 and handle it by hand, see avr.c:avr_expand_builtin().
ID: An integer to identify the built-in.
TYPE: A tree node describing the prototype of the built-in.
ICODE: Insn code number for the insn attached to the built-in.
If special treatment is needed to expand the built-in, set to -1.
