REGRESSION (288911@main-290821@main): RegExp for large input (800KB)
incorrectly returns null

We increase maxRegExpStackSize from 16 MB to 128 MB. This number is
picked because,
1. V8 IRRegExp's max RegExp stack size is 64 MB.
2. Our stack usage is a bit larger than V8.
So, we picked the next power-of-two size, 128 MB. This is still good
compared to unbound size of stack increase.
* JSTests/stress/large-regexp-stack-use.js: Added.
