Initial version of the VulkanAPI, empty and unimplemented.
Successfully builds vk_swiftshader.dll for all platforms/configuration in Visual Studio.

To test using dEQP:
- Edit environment variables
	- Define VK_ICD_FILENAMES to <SwiftShader's source directory>\src\Vulkan\vk_swiftshader_icd.json
- If the location of vk_swiftshader.dll you're using is different than the one specified in
  src\Vulkan\vk_swiftshader_icd.json, modify it to point to the vk_swiftshader.dll file you want to use

Tweak ContextPtr to handle move construction/assignment correctly.
This was overlooked when I made the last minute change to use explicit lock/unlock.

Tweak LockGuard to allow construction from ptr to MutexLock, and behave
correctly if mutex == nullptr. This is required because the locking
machinery for EGL is /outside/ the error generation for bad EGLDisplay.

Add 'Big EGL Lock' around most of the EGL API

This commit removes `sw::Value`, `sw::BasicBlock`, and
`sw::SwitchCases`.  In LLVM 7.0, `llvm::Value`, `llvm::BasicBlock`, and
`llvm::SwitchCases` become final classes, thus we cannot derive from
those classes.  Fortunately, we don't have to derive from them.  We can
explicitly cast the pointers instead.

accessing this array out of bounds, a class was added to make sure
all accesses to the array are done within its bounds.

When a sampler object is bound to a texture unit, it overrides the
texture's filter modes. A texture without mipmaps can thus be complete
even if it has a filter mode which requires mipmaps, if there's a
sampler object with a filter mode which doesn't require mipmaps.
