This is fixing #404 ("windows xp boot takes much longer...")
and several other similar reports.
Changes for v5:
* Include missing hunk in tb_gen_code, as noted in reply to v4.
* Remove helper_check_breakpoints from target/arm/.
* Reorg cflags_for_breakpoints into check_for_breakpoints;
reorg cpu_exec to use a break instead of a longjmp.
* Move singlestep_enabled check from cflags_for_breakpoints
to curr_cflags, which makes cpu_exec_step_atomic cleaner.
Changes for v4:
* Issue breakpoints directly from cflags_for_breakpoints.
Do not generate code for a TB beginning with a BP at all.
* Drop the problematic TranslatorOps.breakpoint_check hook entirely.
Changes for v3:
* Map CF_COUNT_MASK == 0 -> TCG_MAX_INSNS.
* Split out *_breakpoint_check fixes for avr, mips, riscv.
Changes for v2:
* All prerequisites and 7 of the patches from v1 with are merged.
Patches lacking review are all new:
