Here, we had DECL_VALUE_EXPR of a structured binding referring to a
pass-by-invisible-reference parameter, but not being adjusted by
cp_genericize.  We get here because we were looking through a
reference temporary.  Removing that code doesn't seem to break
anything; I'm guessing that it isn't needed anymore because of my
change to support references better in constexpr evaluation.

Tested x86_64-pc-linux-gnu, applying to trunk.
