either THIS or S2 is NULL and is useful for comparing bases when deciding
about memory aliasing.

copy the visibility from the target to get things right.

reset()

void symtab_node::reset ( bool preserve_comdat_group = false )

inherited

As an GCC extension we allow redefinition of the function.  The
semantics when both copies of bodies differ is not well defined.
We replace the old body with new body so in unit at a time mode
we always use new body, while in normal mode we may end up with
old body inlined into some functions and new body expanded and
inlined in others.

??? It may make more sense to use one body for inlining and other
body for expanding the function but this is difficult to do.

This is also used to cancel C++ mangling aliases, which can be for
functions or variables.
