bc9b7656b7 Restrict uniform array flattening to sampler and texture arrays. 
Previously the uniform array flattening feature would trigger on loose
uniform arrays of any basic type (e.g, floats).  This PR restricts it
to sampler and texture arrays.  Other arrays would end up in their own
uniform block (anonymous or otherwise).  (Atomic counter arrays might be an
exception, but those are not currently flattened).

6dbc0a7a33 Support a uniform block to hold global uniform variables. 
Used initially just by HLSL, for $Global.  Could be an option
for GLSL -> Vulkan.

cf43e66125 Fix defects in uniform array flattening 
Fix for two defects as follows:

- The IO mapping traverser was not setting inVisit, and would skip some AST nodes.
  Depending on the order of nodes, this could have prevented the binding from
  showing up in the generated SPIR-V.

- If a uniform array was flattened, each of the flattened scalars from the array
  is still a (now-scalar) uniform.  It was being converted to a temporary.

e0b9debda2 Flatten uniform arrays 
This checkin adds a --flatten-uniform-arrays option which can break
uniform arrays of samplers, textures, or UBOs up into individual
scalars named (e.g) myarray[0], myarray[1], etc.  These appear as
individual linkage objects.

Code notes:

- shouldFlatten internally calls shouldFlattenIO, and shouldFlattenUniform,
  but is the only flattening query directly called.

- flattenVariable will handle structs or arrays (but not yet arrayed structs;
  this is tested an an error is generated).

- There's some error checking around unhandled situations.  E.g, flattening
  uniform arrays with initializer lists is not implemented.

- This piggybacks on as much of the existing mechanism for struct flattening
  as it can.  E.g, it uses the same flattenMap, and the same
  flattenAccess() method.

- handleAssign() has been generalized to cope with either structs or arrays.

- Extended test infrastructure to test flattening ability.

f8e494c18c HLSL: Flatten all input/output structs, regardless of stage.

5e56423046 Front-ends: Remove now defunct afterEOF and related, use scanner's instead. 
Code using atEndOfFile was dead, instead do something useful with
