c++: remove function_p parm from tsubst_copy_and_build
The function_p parameter of tsubst_copy_and_build (added in r69316) is
inspected only in its IDENTIFIER_NODE case, where it controls whether we
diagnose unqualified name lookup failure for the given identifier. But
I think ever since r173965, we never substitute an IDENTIFIER_NODE with
function_p=true for which the lookup can possibly fail, and therefore
the flag is effectively unneeded.
Before that commit, we would incorrectly repeat unqualified lookup for
an ADL-enabled CALL_EXPR at instantiation time, which naturally could
fail and thus motivated the flag. Afterwards, we no longer substitute
an IDENTIFIER_NODE callee when koenig_p is true, so the flag isn't needed
for its original purpose. What about when koenig_p=false? Apparently
we still may have an IDENTIFIER_NODE callee in this case, namely when
unqualified name lookup found a dependent local function declaration,
but repeating that lookup can't fail (ditto for USING_DECL callees).
So this patch removes this effectively unneeded parameter from
tsubst_copy_and_build. It also updates an outdated comment in the
CALL_EXPR case about when we may see an IDENTIFIER_NODE callee with
koenig_p=false.
