Better testing for Stackwalker (#18). r=bryner

 - Test StackwalkerX86 and StackwalkerPPC on the current process, if built
   by a supported compiler (gcc) on a supported (walkable) CPU (x86, ppc).
 - This test is not enabled by default because of certain optimizations
   that interfere with it (stack frame reuse, frame pointer omission).  See
   the comments at the top of stackwalker_selftest.cc.  To enable this
   test in the standard "make check" suite, configure with --enable-selftest.
