target-*: Introduce and use cpu_breakpoint_test

Reduce the boilerplate required for each target.  At the same time,
move the test for breakpoint after calling tcg_gen_insn_start.

Note that arm and aarch64 do not use cpu_breakpoint_test, but still
move the inline test down after tcg_gen_insn_start.
