Revert "Removed Subzero compilation from SwiftShader solution"

It caused building Subzero individually to fail. Instead I've added
a header which will get included when the submodule is not present
and generates an error. The LLVM dependencies were split off into a
separate project to make this work.

This reverts commit d5d886eb1c5502c2b976388742b2bb50d4d0ce65.

Removed Subzero compilation from SwiftShader solution

Removed Visual Studio compilation of Subzero and related tests from
the SwiftShader solution so that building the Solution no longer
attempts to build Subzero, which currently doesn't build in Visual
Studio.

Refactor vector operations.

Subzero does not know the element types of vectors, so pass it as an
argument. Also deprecate createSwizzle() and createMask() from
Nucleus since we only need Float4 Swizzle().
