b0b1974ddd Pull utility routines with no SelectionDAG dependence out of 
SelectionDAGBuilder. FunctionLoweringInfo isn't an ideal place for
them to live, but it's better than SelectionDAGBuilder for now.

bc94b6f1fd Expand postra machine licm's capability a little more. If an instruction's register operands are all loop invariants, then it's safe to hoist it.

a75eedea38 Teach MachineSinking to handle easy critical edges. 
Sometimes it is desirable to sink instructions along a critical edge:

x = ...
if (a && b) ...
else use(x);

The 'a && b' condition creates a critical edge to the else block, but we still
want to sink the computation of x into the block. The else block is dominated by
the parent block, so we are not pushing instructions into new code paths.
