[14/17] parloops: don't request insert that won't be completed

[Alexandre Oliva via Gcc-patches]

In take_address_of, we may refrain from completing a decl_address
INSERT if gsi is NULL, so dnn't even ask for an INSERT in this case.

Regstrapped on x86_64-linux-gnu.  Ok to install?


for  gcc/ChangeLog

        * tree-parloops.cc (take_address_of): Skip INSERT if !gsi.
