base/asm-common.h, ...: Add missing `cmov' instruction (and `.CC' variants).

This instruction conditionally moves a value from one register to
another, otherwise leaving the destination unchanged:

cmov RD, RN, CC == csel RD, RN, RD, CC

Also define `cmov.CC' for all condition codes CC.

Use this to slightly improve `rijndael_setup_arm64_crypto'.
