[PATCH dwarves 0/2] clang true signature follow-on

Though the true signature series [1] has not landed yet, this
is intended as a follow-on series to resolve an issue it raises;
by sharing the optimization detection code it can result in
the non true signature case being overly aggressive in omitting
functions from BTF that have optimized parameters.

See patch 1 for the details; patch 2 tests the change for gcc.

This series applies on top of [1]; the danger is we do not
want to land the true signature series without resolving this
issue first so hopefully folks can test with this series on top to
see if issues are resolved.  CI passed with this series on top
of the true signature series at [2].
