fourthTier: DFG should support op_switch_imm
​https://bugs.webkit.org/show_bug.cgi?id=117559

Reviewed by Oliver Hunt.

Implement integer (i.e. immediate) switches in the DFG. Reduce the minimum
threshold for using op_switch.

Also get rid of edge code support, since we haven't used it in the year since
I introduced it. It was supposed to allow us to break critical edges late in
the backend, thus enabling global register allocation from an SSA-form graph.
But we aren't doing that so I figure we should just kill the code for now. It
would have made implementing switch harder.
