In D121898 we restrict parameter alignment size in IR since DAGISel
only have 4 bits to hold the alignment value. However intrinsics
won't be lowered to call instruction, so we can remove the constrain
for intrinsics.

In DAGISel, the parameter alignment only have 4 bits to hold the value.
The encode(alignment) would plus the shift value by 1, so the max aligment
ISel can support is 2^14. This patch verify the parameter and return
value for alignment.
