Ben Skeggs a6c747e8e0 nir: use bitfield_insert instead of bfi in nir_lower_double_ops 
NVIDIA hardware doesn't have an equivilant to bfi, but we do already have
a lowering for bitfield_insert->bfi.

Caio Marcelo de Oliveira Filho d1f6d2f3e8 nir: Fix logic that ends combine barrier sequence 
The combination must stop when we see a scoped barrier that have
execution scope, i.e. it has control barrier behavior.  The code was
mistakenly looking at the wrong scope.

Boris Brezillon 345b5847b4 nir: Replace the scoped_memory barrier by a scoped_barrier 
SPIRV OpControlBarrier can have both a memory and a control barrier
which some hardware can handle with a single instruction. Let's
turn the scoped_memory_barrier into a scoped barrier which can embed
both barrier types. Note that control-only or memory-only barriers can
be supported through this new intrinsic by passing NIR_SCOPE_NONE to the
unused barrier type.
