Most likely the ICE started when static operator() support (for C++23) came in
via r13-2892-g303976a6076f28 .

c++: Fix up mangling of static lambdas [PR108525]
Before the P1169R4 changes, operator () of a lambda was
always a method, so it was fine to pass method_p = 1 unconditionally,
but it isn't always the case, so this patch adds a check for whether
it is a method or nor.

* mangle.cc (write_closure_type_name): Don't assume all
lambda operator() fns are methods.

Seems when committing the PR108525 fix I've missed that a test with
the same name had been added a few hours before for PR108526.
This patch separates the PR108525 test into a new file.
