This is a reland of 97ed8b27

Original change's description:
> [regexp] Guarantee an allocated regexp stack
> 
> The regexp stack is used during execution of jitted regexp matcher
> code.  Previously, the stack was initially not present / nullptr, and
> we had to explicitly check for this condition and bail out in builtin
> code.
> 
> This CL changes behavior to guarantee a present stack by adding a
> statically-allocated area that is used whenever no
> dynamically-allocated stack exists.
