[JSC] Propagate uint64_t index until we do bound-check for TypedArray
https://bugs.webkit.org/show_bug.cgi?id=321317

Reviewed by Yijia Huang.
It is 32bit only issue. We should propagate uint64_t index until we do
bound check, after that, we can use size_t. In 64bit, it does not matter
since sizeof(uint64_t) == sizeof(size_t).
Test: JSTests/stress/typedarray-put-out-of-range-canonical-numeric-index.js
* JSTests/stress/typedarray-put-out-of-range-canonical-numeric-index.js: Added.
