# Flags:
#   S: has size (use in CONST1, CONST2, CONST4, CONST8 forms)
#   V: has no size (use in JUMP, CJUMP, RET forms)
#
# Types:
#   I, F: integer, float
#   A: any (will be coerced to I or F during IR postprocessing)
#
# Any instruction with an A type must be followed by the corresponding F
# version.
