  make it possible.

  Support call graph profiling.
  Keep upper two bits of PC unchanged through backtrace rather than take
  them from sp (a1). The stack pointer is usually in the same GB (same
  upper 2 bits) as PC, but technically doesn't always have to be (and
  might not in the future, when taking full advantage of MMU v3).
