[JSC] Save source offset for evaluating Wasm constant expressions
https://bugs.webkit.org/show_bug.cgi?id=307841
rdar://166778509
Reviewed by Mark Lam.
Constant expressions may throw exceptions during evaluation, which need the
source offset. This PR saves the source offset until evaluation time so that
errors can be thrown with the correct offset.
Test: JSTests/wasm/stress/const-expr-evaluate-error-offset.js
* JSTests/wasm/stress/const-expr-evaluate-error-offset.js: Added.
