Support ESSL structs containing samplers on D3D
Since HLSL can't natively handle samplers in structs, samplers need to
be extracted out of structs into separate variables in the translated
shader code. In HLSL 4.1, samplers that were in structs go into the
normal sampler arrays and are identified by index constants. In other
HLSL versions, samplers that were in structs are translated as uniform
variables.
These transformations are done inside the HLSL output classes, not as
tree transformations. This helps to keep the uniform API provided by
the shader translator intact.
Wherever a struct containing samplers is passed into a user-defined
function, the translated HLSL code passes the separate sampler
variables alongside a struct where the samplers have been removed.
The D3D backend in libANGLE queries the uniform registers of any
samplers that were in uniform structs, and adds them to the register
maps, so that correct sampler state gets assigned to them.
The extracted sampler variables are prefixed with "angle_" instead of
the usual "_" to prevent any name conflicts between them and regular
variables.

Pass texture base level to shaders on D3D11
The base level is passed to shaders in an array included in the driver
uniform block. This is done on feature levels above 9_3, which treat
samplers as indices to sampler arrays in shaders.
A separate uniform block couldn't be used for the sampler metadata,
since that would bring the number of available uniform blocks down to
below minimum level defined by GLES 3.0.

Redesign samplers in shaders on D3D11
Translation of samplers to HLSL on D3D11 is changed as follows:
Instead of passing around HLSL sampler and HLSL texture references in
shaders, all references to ESSL samplers are converted to constant
indices within the shader body. Each ESSL sampler is identified by an
unique index. In the code generated to implement ESSL texture functions,
these indices are used to index arrays of HLSL samplers and HLSL
textures to get the sampler and texture to use.
HLSL textures and samplers are grouped into arrays by their types. Each
unique combination of a HLSL texture type + HLSL sampler type gets its
own array. To convert a unique sampler index to an index to one of these
arrays, a constant offset is applied. In the most common case of a 2D
texture and a regular (non-comparison) sampler, the index offset is
always zero and is omitted.
The end goal of this refactoring is to make adding extra metadata for
samplers easier. The unique sampler index can be used in follow-up
changes to index an array of metadata passed in uniforms, which can
contain such things as the base level of the texture.
This does not solve the issues with samplers in structs.
The interface from the point of view of libANGLE is still exactly the
same, the only thing that changes is how samplers are handled inside the
shader.
On feature level 9_3, the D3D compiler has a bug where it can report that
the maximum sampler index is exceeded when in fact it is not. This can
happen when an array of samplers is declared in the shader. Because of
this the new approach can't be used on D3D11 feature level 9_3, but it
will continue using the old approach instead.

Replace non-copyable macro with a helper class.
This class provides a simpler scheme for blocking default copy
and assignment operators. It also reduces the amount of code
needed since it's inherited to child classes. This also fixes
the conflict between our macro and the same-named macro in
Chromium code.
