Fix range_on_exit for PHI stmts when there are no other stmts in the block.

last_stmt(bb) returns NULL for blocks which only have PHI stmts, and
range_on_exit would trigger a cache fill all the way to the top of the
program for the SSA_NAME.

* gimple-range.cc (gimple_ranger::range_on_exit): Handle block with
only PHI nodes better.
