The ETC2 decoder already existed in SwiftShader, so this cl hooks it
up in vk::Image. In order to be transparent to the user, any time a
compressed image is created, another image is simultaneously created,
which will eventually contain the decompressed image.

Provides a number of template trait types for Reactor primitive types:

CToReactorT<T> transforms the C-type (T) into a suitable Reactor equivalent. Pointer types are now generalized, allowing for translations of T** types.

IsRValue<T>::value and IsLValue<T>::value are true iff T is of the respective Reactor type.

ReactorType<T> resolves to the corresponding LValue Reactor type for T, where T can be a C-type, RValue or LValue.

ValueOf<T> returns a rr::Value* for a C-value, RValue or LValue. This is now used by a single definition of Return(), fixing bad type coercion which in turn produced illegal LLVM IR.

CanBeUsedAsReturn<T>::value is true iff T can be used as a function return type.
CanBeUsedAsParameter<T>::value is true iff T can be used as a function parameter type.
Function signatures are now statically checked that all parameter types and the return type are valid, providing a human readable error message if an invalid type is used (verified on gcc, clang and msvc).

Added a whole bunch of static asserts in ReactorUnitTests.cpp to sanity check the templates.

This meant that stores to the non-zero'th element would corrupt later allocas.

The third coordinate of the 2D sampling code is only used for 2D array
textures, so we don't compute a filter factor. This used to be taken
advantage of by passing the filter factor of the second coordinate to
the addressing method for the third coordinate, and ensuring that the
addressing mode of this component was ADDRESSING_LAYER even for non-
array textures.

Instead of relying on this brittle hack, just specify a third filter
factor. Now that we elide materialization of single-block variables,
this doesn't take any stack space and is zero overhead to the backend.

Previously only the texture pointer was passed to the sampling routine,

allow splitting them up correctly.

Also refactor getImageSampler to not start the Reactor function
generation, moving it entirely into emitSamplerFunction so that the
latter only has to be passed the pointers to the descriptor state that
will affect the code that's generated.

Name all the parameters according to their actual type.
