This is fixing #404 ("windows xp boot takes much longer...")
and several other similar reports.

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:
  08-target-avr-Advance-pc-in-avr_tr_breakpoint_check.patch
  09-target-mips-Reduce-mips_tr_breakpoint_check-pc-ad.patch
  10-target-riscv-Reduce-riscv_tr_breakpoint_check-pc-.patch
  13-accel-tcg-Encode-breakpoint-info-into-tb-cflags.patch
