[AST] Pack GenericSelectionExpr

Store the controlling expression, the association expressions and the
corresponding TypeSourceInfos as trailing objects.

Additionally use the bit-fields of Stmt to store one SourceLocation,
saving one additional pointer. This saves 3 pointers in total per
GenericSelectionExpr.
