x86 IR has instances of missing or extra implicit operands not caught by tests: pabsb
INSTR_CREATE_pabsb incorrectly creates a 1 dst, 2 src IR instruction. PABSB and variants have only one source and therefore instr_create_1dst_1src should be used.
Currrent code:
#define INSTR_CREATE_pabsb(dc, d, s) instr_create_1dst_2src((dc), OP_pabsb, (d), (s), (d))
