[PATCH-for-8.0 2/3] softmmu: Restrict cpu_check_watchpoint / address_matches to TCG accel

[Philippe Mathieu-Daudé]

Both cpu_check_watchpoint() and cpu_watchpoint_address_matches()
are specific to TCG system emulation. Declare them in "tcg-cpu-ops.h"
to be sure accessing them from non-TCG code is a compilation error.
