Jordan Rupprecht af3ec731d5 [NFC][ARM] Silence unused variable in release builds 2020-08-03 15:21:44 -07:00
David Green 22916481c1 [ARM] Convert VPSEL to VMOV in tail predicated loops 
VPSEL has slightly different semantics under tail predication (it can
end up selecting from Qn, Qm and Qd). We do not model that at the moment
so they block tail predicated loops from being formed.

This just converts them into a predicated VMOV instead (via a VORR),
allowing tail predication to happen whilst still modelling the original
behaviour of the input.
