In the language specification under Decl.Init.Agg, and in #358, we talk about objects and flattened orderings.

We should really have unified definitions earlier in the spec for "object", "subobject", "flattened ordering" and a notion of a non-divisible subobject (a subobject that does not contain subobjects).

Begin specifying object model
9ef8200 
This change begins to define the object model for HLSL and clearly denotes aggregate and non-aggregate types. It provides base definitions for sub-object ordering and scalar elementwise ordering. It also defines non-decomposable objects and stubs out sections for constructon and access control.

HLSL does not currently support user-defined constructors or access control specifiers, however both are used implicitly and denote non-decomposible objects.

Fixes microsoft#372
