    M clang/test/Frontend/fixed_point_add.c

    M clang/test/Frontend/fixed_point_sub.c

  Log Message:
  -----------
  [CodeGen] Use the common semantic for fixed-point codegen, not the result semantic.

Summary:
Using the result semantic is wrong in some cases, such as
unsigned fixed-point + signed integer. In this case, the
result semantic is unsigned and the common semantic is
signed.
