Log:
    PR c++/49264
    * gimple-fold.c (fold_stmt_1): Don't try to fold *& on the lhs
    if stmt folded into nothing.
    * tree-inline.c (fold_marked_statements): If a builtin at the
    end of a bb folded into nothing, just update cgraph edges
    and move to next bb.
    * cgraph.c (cgraph_update_edges_for_call_stmt_node): Allow new_stmt
    to be NULL.  Don't compute count and frequency if new_call is NULL.

    * g++.dg/opt/pr49264.C: New test.
