Serguei Katkov 0c2ce7e21d [CGP] Relax a bit restriction for optimizeMemoryInst to extend scope 
CodeGenPrepare::optimizeMemoryInst contains a check that we do nothing
if all instructions combining the address for memory instruction is in the same
block as memory instruction itself.

However if any of these instruction are placed after memory instruction then
address calculation will not be folded to memory instruction.

The added test case shows an example.
