Compilation to not use a global local variable counter, but a local one

[MikaelMayer]

Summary

I want counters on generated variables be local, not global

Background and Motivation

Currently, to prevent shadowing from hurting compilers, we append a global counter to local variables.
However, at least in C#, when generating the code, the counters are shared across modules, which makes it that half of the modules change if one module is updated. This prevents compilation optimizations.

Proposed Feature

Reset to zero the global counter variable when resolving when entering a module

Alternatives

N/A

[MikaelMayer]

This is harder than it seems because compile names are currently assigned. lazily
