The sw::MAX_SHADER_CALL_STACK_SIZE of the back-end is now statically
passed to an es2::MAX_SHADER_CALL_STACK_SIZE (has to remain equal or

Run some optimization passes before lowering the code, to allow for a
simpler compiler.

Current passes:
- Exhaustively inline functions
- Apply and freeze specialization constants

I expect this set of passes will change somewhat as the
compiler evolves. We may want to stop inlining at some point.

This fixes an issue where es2::Context::drawElements would still try to
read draw data even when there are 0 elements to draw, causing a buffer
overflow on draw data.

This was found by running Android ES3 dEQP under ASAN. The failing tests
are EQP-GLES3.functional.primitive_restart.[begin_restart,
begin_restart_duplicate_restarts, begin_restart_end_restart,
begin_restart_end_restart_duplicate_restarts,
end_restart_duplicate_restarts, duplicate_restarts].*

The crashing dEQP tests cover glDrawElementsInstanced,
glDrawRangeElements, and glDrawElements. These all converge onto
es2::Context::drawElements.

This cl is a minimal implementation of DescriptorPool and
DescriptorSetLayout.

A DescriptorSet itself is just a straight memory pointer.

A DescriptorPool is a memory pool where DescriptorSets are
allocated. The DescriptorPool object itself is little more
than a memory allocator.
A few minor optimizations were made to speed up the default
case:
- The Descriptor pool starts looking for a large enough
  memory block at the end of the pool, which should be optimal
  if the DescriptorSets are allocated linearly
- When allocating multiple DescriptorSets at once, the pool
  first attempts to allocated all of them contiguously. This
  prevents looking for free memory blocks multiple times and
  once again should be optimal if the DescriptorSets are
  allocated linearly

Note: For now, DescriptorSetLayout::GetDescriptorSize() is a
      dummy function which always returns the same size for
      every Descriptor type. This will be implemented properly
      case by case as we add support for new Descriptor types.

Passes all tests in:
dEQP-VK.api.*descriptor*

SPIRV-Tools comes with CMake build files. Integrating it into our
custom Visual Studio solution requires making the project files that
it generates path independent so that they can be checked into the
repository.

This is achieved by the build/cmake.sh shell script that is intended
to be run from the Git Bash shell. It needs to be re-run when any
CMakeLists.txt file changes.

.gitignore was modified to allow for build files under the build/
directory to be checked in. CMakeFiles/ and CMakeCache.txt are ignored
because they contain absolute paths and aren't necessary for building.
