x86: Fix cmov cost model issue [PR109549]
(if_then_else:SI (eq (reg:CCZ 17 flags)
(const_int 0 [0]))
(reg/v:SI 101 [ e ])
(reg:SI 102))
The cost is 8 for the rtx, the cost for
(eq (reg:CCZ 17 flags) (const_int 0 [0])) is 4,
but this is just an operator do not need to compute it's cost in cmov.
gcc/ChangeLog:
PR target/109549
* config/i386/i386.cc (ix86_rtx_costs): The XEXP (x, 0) for cmov
is an operator do not need to compute cost.
gcc/testsuite/ChangeLog:
* gcc.target/i386/cmov6.c: Fixed.
