Combine ignores asm constraints and turns

(asm_operands/v:SI ("int $0x80
") ("=a") 0 [
(reg:SI 65)
(subreg/s/u:SI (reg/v/f:DI 62 [ xxxxx ]) 0)
(subreg/s/u:SI (reg/v/f:DI 63 [ yyyyy ]) 0)
(reg:SI 66)
]
[
(asm_input:SI ("0") (null):0)
(asm_input:SI ("c") (null):0)

(asm_input:SI ("S") (null):0)
]

Things go downhill from here.
