Removes non-static locals collection

[mathetake]

This stops gathering NonStaticLocals during validation phase,
which was previously used to do the "fast pass" on variable search
by the frontend. However, it had no impact after the last mile refactoring
included in 1.7.0 and caused tons of allocations.

As as result, you can see the compilation perf improvements especially
around memory pressure without any impacts on the runtime perf
