c++: fix reporting routines re-entered [PR119303]
We crash while we call warning_at ("inline function used but never defined")
since it invokes dump_template_bindings -> tsubst -> ... -> convert_like ->
... -> c_common_truthvalue_conversion -> warning_at ("enum constant in boolean
context")
cp_truthvalue_conversion correctly gets complain=0 but it calls
c_common_truthvalue_conversion from c-family which doesn't have
a similar parameter.
We can fix this by tweaking diagnostic_context::report_diagnostic to
check for recursion after checking if the diagnostic was enabled.

gcc/ChangeLog:
* diagnostic.cc (diagnostic_context::report_diagnostic): Check for
non-zero m_lock later, after checking diagnostic_enabled.
gcc/testsuite/ChangeLog:
* g++.dg/cpp2a/lambda-uneval26.C: New test.
* g++.dg/warn/undefined2.C: New test.
