Merge pull request #1029 from KhronosGroup/msl-2.2-validation-fix 
Prepare for MSL 2.2 testing

be1e27a6e5 MSL: Conditionally validate MSL 2.2 shaders. 
Travis CI Xcode image does not support MSL 2.2 yet (beta), so just do
local validation for now.

026a167549 MSL: New SDK errors out on cull distance. 
Not supported, so just ignore this test for now, it should not have
compiled in the first place.

d81bfc5b58 MSL: Fix regression with Private parameter declaration. 
If we compile multiple times due to forced_recompile, we had
deferred_declaration = true while emitting function prototypes which
broke an assumption. Fix this by clearing out stale state before leaving
a function.

30bb197a5d MSL: Support remapping constexpr samplers by set/binding. 
Older API was oriented around IDs which are not available unless you're
doing full reflection, which is awkward for certain use cases which know
their set/bindings up front.

Optimize resource bindings to be hashmap rather than doing linear seeks
all the time.

457eba355e Employ heuristics to figure out how to emit SSBO/UAV reflection names. 
This is rather shaky, but we don't have many choices here except add a
lot of awkward and unintuitive options. Try to deduce this from OpSource
and fallback to heuristic.

03d93abc1a Deal with case where a variable is dominated by inner part of a loop. 
There is a risk that we try to preserve a loop variable through multiple
iterations, even though the dominating block is inside a loop.

Fix this by analyzing if a block starts off by writing to a variable. In
that case, there cannot be any preservation going on. If we don't, pretend the
loop header is reading the variable, which moves the variable to an
appropriate scope.

c09ca74c61 Deal with case where a block is somehow emitted in a duplicated fashion. 
We seen to have to deal with a case where a block is used multiple times
without any "proper" structured control flow, so we risk losing deferred
declaration state.

314efdcc42 MSL: Fix declaration of unused input variables. 
In multiple-entry-point modules, we declared builtin inputs which were
not supposed to be used for that entry point.

Fix this, by being more strict when checking which builtins to emit.

7b9e0fb428 MSL: Implement OpArrayLength. 
This gets rather complicated because MSL does not support OpArrayLength
natively. We need to pass down a buffer which contains buffer sizes, and
we compute the array length on-demand.

Support both discrete descriptors as well as argument buffers.

96492648d4 MSL: Fix struct declaration order with complex type aliases. 
MSL generally emits the aliases, which means we cannot always place the
master type first, unlike GLSL and HLSL. The logic fix is just to
reorder after we have tagged types with packing information, rather than
doing it in the parser fixup.

eaf7afed97 MSL: Support argument buffers and image swizzling. 
Change aux buffer to swizzle buffer.
There is no good reason to expand the aux buffer, so name it
appropriately.

Make the code cleaner by emitting a straight pointer to uint rather than
a dummy struct which only contains a single unsized array member anyways.

This will also end up being very similar to how we implement swizzle
buffers for argument buffers.

Do not use implied binding if it overflows int32_t.
