Merge pull request #1505 from cdavis5e/msl-vertex-writes 
MSL: For 2.1+, don't disable rasterization for vertex writes.

1b6b9705e6 MSL: For 2.1+, don't disable rasterization for vertex writes. 
Writing to buffers actually works starting in MSL 2.1 (macOS 10.14,
iOS 12). Writing to textures works starting in MSL 2.2 (macOS 10.15, iOS
13).

No tests unfortunately, because the MSL 2.2 compiler and above produce a
warning that cannot be disabled, because it has no associated option.

1264e2705e MSL: Cast broadcast booleans to ushort. 
Metal doesn't support broadcasting or shuffling boolean values, but we
can work around that by casting it to `ushort`, then casting it back to
`bool`. I used `ushort` instead of `uint` because 16-bit values give
better throughput on Apple GPUs.

065b5bda3c MSL: Mask ballots passed to Ballot bit ops. 
Only the least *n* bits are significant, where *n* is the subgroup size.
The Vulkan CTS actually checks this.

The `FindLSB` tests weren't actually failing, but I masked that anyway,
in case there's some corner case the CTS is missing.

781367d083 MSL: Support vectors with OpGroupNonUniformAllEqual. 
This was not tested here in SPIRV-Cross. Predictably, it broke when I
tried it in the CTS.

6ccb902462 MSL: Correct definitions of subgroup ballot mask variables. 
`SubgroupEqMask` had a fencepost error that gave wrong values for
invocation ID 32.

For `SubgroupGeMask` and `SubgroupGtMask`, I forgot to shift the values
from `extract_bits()` up so that the mask is in the correct position.
Using `insert_bits()` instead should fold these two operations into one.

`SubgroupLtMask` and `SubgroupLeMask` were already correct.

3e6010d8c5 MSL: Don't use a bitcast for tessellation levels in tesc shaders. 
`half` cannot be bitcasted to `float`, because the two types are not the
same size. Use an expanding cast instead.

We were already doing this for stores to the tessellation levels; why I
didn't also do this for loads is beyond me.

21d38f74ce MSL: Fix calculation of atomic image buffer address. 
Fix reversed coordinates: `y` should be used to calculate the row
address. Align row address to the row stride.

I've made the row alignment a function constant; this makes it possible
to override it at pipeline compile time.

Honestly, I don't know how this worked at all for Epic. It definitely
didn't work in the CTS prior to this.

2219c4a392 MSL: Support SPV_EXT_demote_to_helper_invocation for MSL 2.3. 
MSL 2.3 has everything needed to support this extension on all
platforms. The existing `discard_fragment()` function was given demote
semantics, similar to Direct3D, and the `simd_is_helper_thread()`
function was finally added to iOS.

I've left the old test alone. Should I remove it in favor of these?

66afe8c499 Implement a simple evaluator of specialization constants. 
In some cases, we need to get a literal value from a spec constant op.
Mostly relevant when emitting buffers, so implement a 32-bit integer
scalar subset of the evaluator. Can be extended as needed to support
evaluating any specialization constant operation.
