LOG: [OpenCL] Improve OpenCL operator tests

Extend testing of increment/decrement operators and make sure these
operators are tested in only one dedicated test file.

Rename logical-ops.cl to operators.cl, as it was already containing
more than just logical operators.

Add testing for the remainder operator on floating point types.

Added: 
    clang/test/SemaOpenCL/operators.cl

Modified: 
    clang/test/SemaOpenCL/invalid-vector-literals.cl
    clang/test/SemaOpenCL/vector_inc_dec_ops.cl

Removed: 
    clang/test/SemaOpenCL/logical-ops.cl
