re PR c++/49264 (Internal compiler error: segmentation fault)
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.
