set the alignment of mlir::AttributeStorage to 64 bit explicitly to fix 32 bit platform
On some platform (like WebAssembly), alignof(mlir::AttributeStorage) is 4 instead of 8. As a result, it makes the program crashes since PointerLikeTypeTraits<mlir::Attribute>::NumLowBitsAvailable is 3.
So I explicitly set the alignment of mlir::AttributeStoarge to 64 bits, and set PointerLikeTypeTraits<mlir::Attribute>::NumLowBitsAvailable according to it.
I also fixed an another related error (alignof(NamedAttribute) -> alignof(DictionaryAttributeStorage)) based on reviewer's comments.
