Andreas Kling 5674f8bbe0 LibJS: Limit eval() deoptimization to the containing function scope 
Previously, when direct eval() was called, we would mark the entire
environment chain as "permanently screwed by eval", disabling variable
access caching all the way up to the global scope.

This was overly conservative. According to the ECMAScript specification,
a sloppy direct eval() can only inject var declarations into its
containing function's variable environment - it cannot inject variables
into parent function scopes.

This patch makes two changes:

1. Stop propagating the "screwed by eval" flag at function boundaries.
   When set_permanently_screwed_by_eval() hits a FunctionEnvironment or
   GlobalEnvironment, it no longer continues to outer environments.

2. Check each environment during cache lookup traversal. If any
   environment in the path is marked as screwed, we bail to the slow
   path. This catches the case where we're inside a function with eval
   and have a cached coordinate pointing to an outer scope.

The second change is necessary because eval can create local variables
that shadow outer bindings. When looking up a variable from inside a
function that called eval, we can't trust cached coordinates that point
to outer scopes, since eval may have created a closer binding.

This improves performance for code with nested functions where an inner
function uses eval but parent functions perform many variable accesses.
The parent functions can now use cached environment coordinates.

All 29 new tests verify behavior matches V8.
