Original issue's description:
> Set the stack limit size based on estimated sizes.
> 
> To check if the stack memory has enough room for recursive
> calls, we tried to allocate a large object and assumed the size.
> This CL estimate the real thread stack limit using APIs.
> On some platforms where such APIs do not work correctly,
> we set the limit using the old algorithm.
> 
> ---
> This CL is re-land of https://codereview.chromium.org/910663002/
> and https://codereview.chromium.org/927213002/.
