supposedly wanted to avoid wrapping this and does so by checking that it is a
PARM_DECL with this_identifier as name, but in this case this is not a
PARM_DECL, but build_capture_proxy created VAR_DECL instead.

So, allowing there also VAR_DECL with this_identifier fixes this, but no idea
whether it is desirable to do, and if so, whether just in lambda.c or for all
is_this_parameter uses.
