Test for ultima

[LWisteria]

There is no test for ultima itself. That absence could be problem.

@vorj I request you to try this issue.

@LWisteria I made the template of test case for ultima in #202. Then, what should we check? Please let me know your opinion.

These are the test cases what I conceived:

• General conversions
  • [x] Type cast
    • [x] Function style cast
    • [x] C++ cast
  • [x] Constructor
  • [x] Template instantiation
  • [x] Overload mangling
  • [x] Tricking half
• Specific Conversions
  • [x] CArray<T, N> to __global T*, CArray_N
  • [ ] Operator overloading for CArray
  • [x] Member functions for CArray and CIndexer
  • [ ] Header name mutation
  • [ ] Begin/end print out directives
  • [ ] Elementwise/reduction kernel conversion

@vorj Firstly, do not send the big PR which contains whole cases. #202 (and a item you wrote above) is enough to merge. So please make those tests.

On the other hand, I will check the test cases, at latest before you finish the above cases.

[LWisteria]

Anyway, this issue is not on the beta2 milestone thus #153 's priority is higher.

[vorj]

OK, so I will create those test cases later.

@vorj The file for ultima test will be large. How about making ultima_tests directory and dividing them into each file by test type?
