76; We used to generate really horrible code for this function. The main cause was
77; a lack of a custom lowering routine for an ISD::SELECT. This would result in
78; two "it" blocks in the code: one for the "icmp" and another to move the index
79; into the constant pool based on the value of the "icmp". If we have one "it"
80; block generated, odds are good that we have close to the ideal code for this:
