instead of decoding time.

Continuation of #95899.
The last time it caused some ICEs from generator use, but not everything seems ok.

Overall result: ❌ regressions - no action needed

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.

// For non-reexport variants add their fictive constructors to children.
// Braced variants, unlike structs, generate unusable names in value namespace,
// they are reserved for possible future use. It's ok to use the variant's id as
// a ctor id since an error will be reported on any use of such resolution anyway.

Could we get rid of this special case by giving a dedicated NodeId and LocalDefId to the ctor of struct variants that is different from the struct variant itself?
