Hi!
DECL_OMP_PRIVATIZED_MEMBER VAR_DECLs aren't capture proxies, handling them
that way results in various ICEs.
Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux,
committed to trunk.

* lambda.c (is_capture_proxy): Don't return true for
DECL_OMP_PRIVATIZED_MEMBER artificial vars.
* testsuite/libgomp.c++/pr88988.C: New test.
