x/tools/gopls: Rename: "unexpected composite literal type %T: %v" panic in satisfy.(*Finder).Find

[adonovan]

#!stacks
"runtime.gopanic" && "satisfy.(*Finder).expr:+65"

Issue created by stacks.

This crash indicates that satisfy was called on ill-typed code. Perhaps the best fix is to wait until #70638 is available and then change rename to avoid using the satisfy package entirely, as the type-checker will record this information as it goes.
