    A clang/test/CodeGen/fixed-point-tbaa.c

  Log Message:
  -----------
  Fix TBAA for unsigned fixed-point types

Summary:
Unsigned types can alias the corresponding signed types. I don't see
that this is explicitly mentioned in the Embedded-C specification, but
I think it should work the same as for the integer types.
