[PATCH 0/3] Use code cache in arm and aarch64 prologue analyzer

[Yao Qi <qiyaoltc@gmail.com>]

This patch series improves the speed on setting a breakpoint on a
function, like "break foo" on arm and aarch64.  Each backend has
slightly different paths on "debug information exists vs. debug
information doesn't exist".  Patch #1 changes gdb.perf/skip-prologue.exp
so that we can compile the test case with and without debug
information.  Patch #2 and patch #3 improves arm and aarch respectively.

*** BLURB HERE ***

Yao Qi (3):
  Compile gdb.perf/skip-prologue.c with and without debug info
  Use code cache in arm prologue analyzer
  Use code cache in aarch64 prologue analyzer
