SjoerdMeijer created this revision.
Herald added a subscriber: klimek.
This adds _Float16 as a source language type. As a first step, _Float16 behaves
the same as __fp16 and is thus an alias. This means that _Float16 also behaves
like a storage-only type. Subsequent patches will implement the proper
semantics of both types.
