Kernel callables v3 edit0.2
- Changes towards the "new" standardization of argument matching in callable kernels.
- Changes in the fortran frontend to emit valid loopy kernels obeying the argument matching rules.
- "is_output_only" is not enough to have a deterministic matching pattern, solved by splitting it into 2 attributes i.e. is_output and is_input and added a strategy for loopy to guess these attributes when unspecified by the user.
