metagn ca5df9ab25 wrap fields iterations in if true scope [backport] (#24343)
fixes #24338

When unrolling each iteration of a `fields` iterator, the compiler only
opens a new scope for semchecking, but doesn't generate a node that
signals to the codegen that a new scope should be created. This causes
issues for reused template instantiations that reuse variable symbols
between each iteration, which causes the codegen to generate multiple
declarations for them in the same scope (regardless of `inject` or
`gensym`). To fix this, we wrap the unrolled iterations in an `if true:
body` node, which both opens a new scope and doesn't interfere with
`break`.

Nim Compiler

  • This directory contains the Nim compiler written in Nim.
  • Note that this code has been translated from a bootstrapping version written in Pascal.
  • So the code is not a poster child of good Nim code.
