In #<!-- -->128754, `DataLayoutTypeInterface` was changed to give 
`getPreferredAlignment` a default implemention.  As a result, table-gen no 
longer declared `getPreferredAlignment` when defining a class that contained 
`[DeclareTypeInterfaceMethods&lt;DataLayoutTypeInterface&gt;]` in the table-gen 
definition.  That means all of the definitions in `CIRTypes.cpp`, such as 
`PointerType::getPreferredAligment`, were compilation errors.

Delete all the definitions of `getPreferredAlignment`.  I verified that the 
default implementation does the exact same thing as the explicit overrides that 
are being deleted.
