Anton Johansson 2dd5b7a1b9 accel/tcg: Move jmp-cache CF_PCREL checks to caller
tb-jmp-cache.h contains a few small functions that only exist to hide a
CF_PCREL check, however the caller often already performs such a check.

This patch moves CF_PCREL checks from the callee to the caller, and also
removes these functions which now only hide an access of the jmp-cache.
