The new Store() helper function can store Operand instances independent
from SPIR-V instructions. This allows reuse of this logic for other
instructions that need to store to memory, like Modf and Frexp.

The Operand class is a low-level abstraction of rvalues and constants.
It should not carry the SPIR-V type ID. We only need the size in

This patch modifies the CMakeLists.txt file and a few sources
in order to build the SwiftShader Vulkan ICD for Fuchsia with
CMake.

Note that building EGL/GLES_CM/GLESv2 and tests is not supported,
and should be explicitly disabled when configuring the build,
e.g.:

  mkdir build-fuchsia && build-fuchsia
  cmake .. \
    -DCMAKE_TOOLCHAIN_FILE=.../FuchsiaSdkToolchain.cmake \
    -DCMAKE_BUILD_TYPE=Release \
    -DSWIFTSHADER_BUILD_TESTS=0 \
    -DSWIFTSHADER_BUILD_EGL=0 \
    -DSWIFTSHADER_BUILD_GLES_CM=0 \
    -DSWIFTSHADER_BUILD_GLESv2=0 \
    <other-cmake-options>

  make  # or ninja

NOTE: This should not affect the build for other platforms!

This will make it easier to conditionally add Fuchsia-specific
sources to the build (see discussion on b/144687651 for details).

The BUILD.gn file will still be maintained in parallel for
Fuchsia-specific changes.

NOTE: As of now, the Fuchsia SDK doesn't provide a way for
      third-party code to access the framebuffer directly.

      Instead, client code should rely on Vulkan presentation
      surfaces or higher-level APIs provided by the compositor
      that are still in flux / unstable. Hence this will appear
      in a future CL.
