107ab7c2b7 MSL: Avoid packed arrays in more cases. 
Extend the array stride relaxation to non-packed arrays as well, as
long as the array in question contains a single array element.

0ebb88cc39 MSL: Redirect member indices when buffer has been sorted by Offset. 
If a buffer rewrites its Offsets, all member references to that struct
are invalidated, and must be redirected, do so in to_member_reference,
but there might be other places where this is needed. Fix as required.
SPIR-V code relying on this is somewhat questionable, but seems to be
in-spec.

5e5d1c27ce GLSL: Support f16x2 <-> f32 bitcast. 
There is no native formulation, so introduce a concept of a "complex"
bitcast to handle odd-ball cases which have no native unary operation.

f8592ecdfc MSL: Deal correctly with initializers on Private variables. 
Do not attempt to defer declaration. It would happen to work in most
cases, but the edge case is where the first thing that happens to a
variable is being OpStore'd into.

17ad62eea4 MSL: Support edge case with DX layout in scalar block layout. 
DX may emit ArrayStride and MatrixStride of 16, but the size of the
object does not align with that and expect to pack other members inside
its last member.

The workaround is to emit array size/col/row one less than we expect and
rely on padding to carve out a "dead zone" for the last member.

d9d3359ffb MSL: Deal with cases where builtin is implicitly needed, declared, but unused. 
We need to make sure any builtins which are declared and unused are
emitted as active variables.

f79c1e2fed Deal with illegal names in types as well. 
- Fixes issue with clip_distance flattening in MSL where member to
  flatten from would come from to_member_name, where it should have used
  the builtin name directly. This member name was modified by this patch
  and broke clip distance test shaders.

- Some cleanups with ir.meta, use ir.find_meta instead to not create
  unnecessary hashmap nodes.

d1479f871a MSL: Do not generate UnsafeArray<> for any array inside buffer objects. 
This avoids a lot of huge code changes.
Arrays generally cannot be copied in and out of buffers, at least no
compiler frontend seems to do it.

Also avoids a lot of issues surrounding packed vectors and matrices.

a0c13e4ee8 Do not consider aliased struct types if the master is not a block. 
It is possible for a shader to declare two plain struct types which
simply share the same OpName without there being an implicit
value/buffer alias relationship.

For to_member_name(), make sure to use the type alias master when
resolving member names. The member name may be different in a type alias
master if the SPIR-V is being intentionally difficult.

cf1bf1c6ae Update external/ to SPIR-V 1.5 
Rolled the hashes used for glslang, SPIRV-Tools, and SPIRV-Headers to
HEAD, which includes the update to 1.5.

Added passing '--amb' to glslang, so I didn't have to explicitly set
bindings in a large number of test shaders that currently don't, and
now glslang considers them invalid.

Marked all shaders that no longer pass spirv-val as .invalid.
