  Log Message:
  -----------
  [GC] Made an internal static function into a macro.

This function was used in two hot paths, so aggressive compiler inlining
wouldn't work. Now it's a handful of extra instructions in right places. As a
bonus, it avoids a couple of unnecessary function calls. The end result should
be slightly faster allocation code.

  -----------
  [GC] Optimized stack-walking owned pointer finder.

Avoiding math instructions for an O(n) algorithm helps greatly, but stack
walking is still expensive. This improves the gc_waves_sizeable_headers.pasm
benchmark by 0.8%, which indicates this function costs about half of what it
did previously.
