  [AST] Use canonical constraint declaration for ASTContext::getAutoType

When we do profiling in ASTContext::getAutoType, it wouldn't think about
the canonical declaration for the type constraint. It is bad since it
would cause a negative ODR mismatch while we already know the type
constraint declaration is a redeclaration for the previous one. Also it shouldn't be
bad to use the canonical declaration here.
