Despite the name, PARAMETER_FLOAT4LITERAL is used for integer and
Boolean constants in the ASM representation of GLSL compiled shaders.
Reactor can turn sNaN values into qNan when constructing Float
constants, and thus integers bitcast from a float which were initialized
from a reinterpreted integer may not preserve its original bit pattern.

Instead construct the Float register values from Reactor Ints which are
bitcast to Float.

When building the vulkan library (libvk_swiftshader.so) for Fuchsia,
do not place the stripped binary to $OUT_DIR/swiftshader/ instead of
its default location (i.e. $OUT_DIR/lib/).

That's because the Fuchsia packaging scripts rely on the location
of the unstripped library ($OUT+DIR/lib.unstripped/) to find the
release one (i.e. by replacing 'lib.unstripped' with 'lib').

This resulted in a build error (see bug for details). This CL
works around the issue rather than fixing the scripts.

A few changes were made to make this work:
- activeLaneMask now contains cMask. Since it's only used in
  loads, stores and atomics, it should be fine to include it
- Added a storesAndAtomicsMask, which also contains sMask
  (stencil) and zMask (depth) for early fragment tests.
  The mask affects all atomic operations and store operations
  into storage buffer and images.
- support for spv::BuiltInHelperInvocation was added
