Sanjay Patel 544843cee1 prevent folding a scalar FP load into a packed logical FP instruction (PR22371)
Change the memory operands in sse12_fp_packed_scalar_logical_alias from scalars to vectors. 
That's what the hardware packed logical FP instructions define: 128-bit memory operands.
There are no scalar versions of these instructions...because this is x86.

Generating the wrong code (folding a scalar load into a 128-bit load) is still possible
using the peephole optimization pass and the load folding tables. We won't completely
solve this bug until we either fix the lowering in fabs/fneg/fcopysign and any other
places where scalar FP logic is created or fix the load folding in foldMemoryOperandImpl()
to make sure it isn't changing the size of the load.
