This patch intends to implement the creation of a geometry shader
and attaching a geometry shader to a program on OpenGL back-ends.

This patch also adds all geometry shader related dEQP-GLES31 test
failures to deqp_gles31_test_expectations.txt.

If we can make the index range computation happen as late as possible,
we won't have to check it during the fastest draw call paths.

This change makes it easier to skip re-computing some index range
checks by only checking it in one place in IndexDataManager, and by
making it a lazy check; the check is never evaluated if the primitive
restart workaround is not enabled.

Future work can also push the index range computation for vertex info
later, so we only evaluate it in the cases where we need it.

Unreferenced local and global variables are now pruned from the AST.
They will be removed unless their initializer has side effects.

The CollectVariables step needs to be run after the pruning, as the
pruning may affect which interface variables are statically used.

It's also good to gather built-ins that need to be emulated after the
pruning, so unnecessary built-in emulation functions are not added to
the translator output.

This will help handle some dEQP tests for arrays of arrays that have
extremely large local arrays that are only used in an array length
query. By constant folding the length and pruning unused variables we
will avoid adding a large amount of array initialization code to the
generated shaders.

Previously, creating nodes for initializing each single array element
could result in memory bloat during translation when dealing with
large arrays. The resulting shader could also end up very long.
Initialize most arrays using a simple for loop instead. The loop is
compatible with ESSL 1.00 Appendix A limitations.

An exception is made for fragment outputs, so that they are not
indexed by non-constant values.

On some platforms using the a loop to initialize variables can cause
problems, so we also have a compiler flag for turning this behavior
off. The flag was already added earlier for a staggered rollout of
this functionality.

Clang build with dEQP.

This uses the existing dirty bit mDirtyImages to early return in the

Also fixes a couple missing cases for setting dirty images. The code
could be improved in the future by using a bitset of dirty images per
mip level instead of a single bit.
