OpenCL-CTS/test_conformance/math_brute_force/binary_half.cpp
Chuang-Yu Cheng 5749818906 math_brute_force: fix fdim to use device's rounding when converting result back to half. (#2223) 
In the half-precision `fdim` test, the original code used `CL_HALF_RTE`
to convert the float result back to half, causing a mismatch in
computation results when the hardware uses RTZ. Some of the examples:
```
  fdim(0x365f, 0xdc63) = fdim( 0.398193f,  -280.75f)     =   281.148193f (RTE=0x5c65, RTZ=0x5c64)
  fdim(0xa4a3, 0xf0e9) = fdim(-0.018112f, 10056.0f)      = 10055.981445f (RTE=0x70e9, RTZ=0x70e8)
  fdim(0x1904, 0x9ab7) = fdim( 0.002449f,    -0.003279f) =     0.005728f (RTE=0x1dde, RTZ=0x1ddd)
```

Fixed this by using the hardware's default rounding mode when converting
the result back to half.
