[PATCH] Remove obsolete alias check in cgraph_redirect_edge_call_stmt_to_callee

[Martin Jambor]

Hi,

since (same body) aliases have their own cgraph_nodes, the check for
them in cgraph_redirect_edge_call_stmt_to_callee is now unnecessary
because e->callee is now the alias, not the function node.

The following patch therefore removes it.  Bootstrapped and tested on
x86_64-linux, OK for trunk?

Thanks,

Martin
