…l evaluator Fixes that the partial evaluator was interpreting initializer-less enum members as undefined. In this case the value is the same as the index.
When we generate an HMR replacement function, we determine which locals from the file are used and we pass them by reference. This works fine in most cases, but breaks down for const enums which don't have a runtime representation. These changes work around the issue by passing in all the values as an object literal. Fixes angular#59800.
…d through Adds some logic so that if we can't produce a runtime representation of an enum, the dev server can fall back to refreshing the page.

Includes the following changes that allow us to generate HMR replacement functions that depend on const enums.
fix(compiler-cli): handle enum members without initializers in partial evaluator
Fixes that the partial evaluator was interpreting initializer-less enum members as undefined. In this case the value is the same as the index.
fix(compiler-cli): handle const enums used inside HMR data
When we generate an HMR replacement function, we determine which locals from the file are used and we pass them by reference. This works fine in most cases, but breaks down for const enums which don't have a runtime representation.
These changes work around the issue by passing in all the values as an object literal.
fix(compiler-cli): gracefully fall back if const enum cannot be passed through
Adds some logic so that if we can't produce a runtime representation of an enum, the dev server can fall back to refreshing the page.
Fixes #59800.
