[ESNext] Enables a way to throw an error on ByteCodeGenerator step
https://bugs.webkit.org/show_bug.cgi?id=180139

Reviewed by Mark Lam.

JSTests:

* stress/eval-huge-big-int-memory-overflow.js: Added.

Source/JavaScriptCore:

This is a minimal fix that only deals with overly huge BigInts.
A more thorough solution is rather low priority (since it has neither securities nor performance impact).

(JSC::BytecodeGenerator::addBigIntConstant):
* bytecompiler/NodesCodegen.cpp:
(JSC::ConstantNode::emitBytecode):
