Herald added a project: LLVM.

This adjusts all the MVE and CDE intrinsics now that v2i1 is a legal type, to use a <2 x i1> as opposed to emulating the predicate with a <4 x i1>. The v4i1 workarounds have been removed leaving the natural v2i1 types, notably in vctp64 which now generates a v2i1 type.

AutoUpgrade code has been added to upgrade old IR, which needs to convert the old v4i1 to a v2i1 be converting it back and forth to an integer with arm.mve.v2i and arm.mve.i2v intrinsics. These should be optimized away in the final assembly.
