[Bug c/13856] [3.4/3.5 Regression] hidden support broken with builtin functions

The source code is fine.  I think what needs to happen is that the various
special cases for builtin functions should only apply if the builtin is still
invisible (C_DECL_INVISIBLE (olddecl)) -- if it is visible, then there was a
declaration in the source code, and following declarations must agree with that one.
