Stack trace

When using Clang 13 and trunk (checked on godbolt), invoking a naked lambda
causes a segmentation fault in the frontend during codegen for it.

Example code (tested with -std=c++2b -Wall -Wextra -Wpedantic):
void f() {
    [] [[gnu::naked]] {}();

Attached is the stack trace from Clang 13.
