New Revision: 51396

URL: http://llvm.org/viewvc/llvm-project?rev=51396&view=rev
Log:
Add a Type::isSingleValueType method. This will be used by code
that currently uses Type::isFirstClassType and depends on it
returning false for struct or array types.

This commit doesn't change the behavior of Type::isFirstClassType.
