Subject: [PATCH] Fix lambdas in template default argument of inherited ctor. (backport for PR 81860)
Authentication-results: sourceware.org; auth=none

This is a backport of r251426 which incidentally fixed PR 81860 and
its dup. The bug was closed as fixed, but as a regression it should be
fixed for 7.x too.

The patch applied cleanly to the branch except for a minor conflict in
get_defaulted_eh_spec because r250994 isn't on the branch.

Tested x86_64-linux, OK for gcc-7-branch?
