Implement OpenCL binary operations
This implements various OpenCL binary operations, adding a new template class to do so. gdb/ChangeLog 2021-03-08 Tom Tromey <tom@tromey.com> * opencl-lang.c (opencl_relop, eval_opencl_assign): No longer static. Change parameters. (eval_opencl_assign): No longer static. Add "op" parameter. (evaluate_subexp_opencl): Update. * c-exp.h (opencl_binop_operation): New template class. (opencl_assign_operation, opencl_equal_operation) (opencl_notequal_operation, opencl_less_operation) (opencl_gtr_operation, opencl_geq_operation) (opencl_leq_operation): New typedefs.
