Introduce a spelling index to Attr class, which is an index into the attribute spelling list of an attribute defined in Attr.td.
This index will determine the actual spelling used by an attribute, as it incorporates both the syntax and naming of the attribute.
When constructing an attribute AST node, the spelling index is computed based on attribute kind, scope (if it's a C++11 attribute), and
name, then passed to Attr that will use the index to print itself.
Thanks to Richard Smith for the idea and review.

This submission improves Clang sema handling by using Clang tablegen
to generate common boilerplate code. As a start, it implements AttributeList
enumerator generation and case statements for AttributeList::getKind.
A new field "SemaHandler" is introduced in Attr.td and by default set to 1
as most of attributes in Attr.td have semantic checking in Sema. For a small
number of attributes that don't appear in Sema, the value is set to 0.
Also there are a small number of attributes that only appear in Sema but not
in Attr.td. Currently these attributes are still hardcoded in Sema AttributeList.
