[ARM][MVE] Refactor option -disable-mve-tail-predication

Authored by SjoerdMeijer on Jul 3 2020, 7:45 AM.



This refactors option -disable-mve-tail-predication to take different arguments so that we have 1 option to control tail-predication rather than several different ones.

This is also a prep step for D82953, in which we want to reject reductions unless that is requested with this option.

Sounds good to me. It may get a bit unwieldy to have one option with many preferences, but looks OK with these ones.

Thanks, and yes, we can/should revise this later. For now this should be an improvement, because I needed 3 different options for tail-predication, which was a becoming unwieldy :-) It should only become simpler from now on as reductions are a special case at the moment, but that should disappear at some point.
