optabs: Remove cmov optab [PR120230]
cmov optab was added back in r0-24110-g1c0290eaac4094
(https://gcc.gnu.org/pipermail/gcc-patches/1999-September/018596.html)
but it was never used. movcc is used instead and since r0-93453-gf90b7a5a7913cc (cond-optab),
movcc becomes what cmov_optab was going to be; in having a combined compare and move optab.
Note the only target which seems to have implemented this optab is aarch64; will remove
that in a different patch.
Bootstrapped and tested on x86_64-linux-gnu.
PR middle-end/120230
gcc/ChangeLog:
* optabs.cc (can_compare_p): Remove support for ccp_cmov.
* optabs.def (cmov_optab): Remove.
* optabs.h (can_compare_purpose): Remove ccp_cmov.
