[X86] Fix a nullptr dereference in X86Subtarget::classifyLocalReference when compiling with -mcmodel=medium -fpic and using a constant pool

LowerConstantPool passes a nullptr into classifyLocalReference. The medium code model handling for PIC will try to deference it using isa. This patch switches to isa_and_nonnull.
