Revert of Oilpan: Query stack frame register instead of manual bookkeeping

Revert of Oilpan: Query stack frame register instead of manual bookkeeping (patchset #8 id:130001 of https://codereview.chromium.org/818253005/)

Reason for revert:
Maybe causing debug build asserts

Original issue's description:
> Oilpan: Query stack frame register instead of manual bookkeeping
> 
> This CL introduce new class StackFrameDepth to keep track of
> current stack frame depth.
> On supported ABI/compiler, StackFrameDepth queries current
> stack frame base register (e.g. %rbp on X86_64), skipping manual
> bookkeeping.
> 
> This improves Oilpan marking time by 17% on
> BlinkGC.stress-large-SVGLengthList.html.
> 
> TEST=PerformanceTests/BlinkGC/stress-large-SVGLengthList.html
> BUG=420515

LGTM, thanks for reverting this. Let's stabilize our trees first.

Always use an explicit marking stack when processing the weak callbacks to a
fixed point, might be worth considering.
