Bug 23062 – [jsfunfuzz] Computed exception offset wrong when first instruction is attempt to resolve deleted eval

• Status: RESOLVED
• Resolution: FIXED
• Component: JavaScriptCore

[Oliver Hunt]

delete eval;
(function(){ try { eval("") } catch(e) { print("ARGHH!!!") } })()

Results in an assertion failure as it fails to find the correct handler offset when resolving eval fails.

[Oliver Hunt]

Have fix, we weren't correctly emitting position information for the resolve of "eval" in the eval call node.  Just making tests.

Nice and easy fix
