Matthew Dempsky fa9efd9171 cmd/compile/internal/noder: correct positions for synthetic closures 
When inlining functions that contain function literals, we need to be
careful about position information. The OCLOSURE node should use the
inline-adjusted position, but the ODCLFUNC and its body should use the
original positions.

However, the same problem can arise with certain generic constructs,
which require the compiler to synthesize function literals to insert
dictionary arguments.

go.dev/cl/425395 fixed the issue with user-written function literals
in a somewhat kludgy way; this CL extends the same solution to
synthetic function literals.

This is all quite subtle and the solutions aren't terribly robust, so
longer term it's probably desirable to revisit how we track inlining
context for positions. But for now, this seems to be the least bad
solution, esp. for backporting to 1.20.

Updates #54625.
Fixes #58513.
