* qemu/tcg: check for UC_HOOK_MEM_READ_AFTER.

Use has_hookmem() helper to determine wether "slow-path" TLB read is
needed. Add this helper to x86 architecture as well so that to check for
all hookmem.

* qemu/tcg: factor out has_hookmem().

It's the same implementation for all architectures, so factor out
has_hookmem() into tcg_uc_has_hookmem().
