Currently, there are some inconsistencies to how clause arguments are named in the OpenMP dialect. Additionally, the clause operand structures associated to them also diverge in certain cases. The purpose of this patch is to normalize argument names across all `OpenMP_Clause` tablegen definitions and clause operand structures. This has the benefit of providing more consistent representations for clauses in the dialect, but the main short-term advantage is that it enables the development of an OpenMP-specific tablegen backend to automatically generate the clause operand structures without breaking dependent code. The main re-naming decisions made in this patch are the following: - Variadic arguments (i.e. multiple values) have the "_vars" suffix. This and other similar suffixes are removed from array attribute arguments. - Individual required or optional value arguments do not have any suffix added to them (e.g. "val", "var", "expr", ...), except for `if` which would otherwise result in an invalid C++ variable name. - The associated clause's name is prepended to argument names that don't already contain it as part of its name. This avoids future collisions between arguments named the same way on different clauses and adding both clauses to the same operation. - Privatization and reduction related arguments that contain lists of symbols pointing to privatizer/reducer operations use the "_syms" suffix. This removes the inconsistencies between the names for "copyprivate_funcs", "[in]reductions", "privatizers", etc. - General improvements to names, replacement of camel case for snake case everywhere, etc. - Renaming of operation-associated operand structures to use the "Operands" suffix in place of "ClauseOps", to better differentiate between clause operand structures and operation operand structures. - Fields on clause operand structures are sorted according to the tablegen definition of the same clause. The assembly format for a few arguments is updated to better reflect the clause they are associated with: - `chunk_size` -> `dist_schedule_chunk_size` - `grain_size` -> `grainsize` - `simd` -> `par_level_simd`
