Juergen Ributzka	296833cde9	[FastISel][X86] Only fold the cmp into the select when both instructions are in the same basic block.

This can happen when one of the operands to the cmp is a load and the load gets folded into the cmp.

[FastISel][X86] Only fold the cmp into the select when both instructions are in the same basic block.

If the cmp is in a different basic block, then it is possible that not all
operands of that compare have defined registers. This can happen when one of
the operands to the cmp is a load and the load gets folded into the cmp. In
this case FastISel will skip the load instruction and the vreg is never
defined.
