Promote and fold indexing nodes similarly to other binary ops
Indexing nodes now get their type set in TIntermBinary::promote, same
as math and logic ops. They are also constant folded through
TIntermBinary::fold() instead of having special functions for constant
folding them in ParseContext.
Index nodes for struct and interface block member access now always
have integer type, instead of sometimes having the type of the field
they were used to access.
Usage of TIntermBinary constructor is cleaned up so only the
constructor that takes in left and right operands is used. The type
of TIntermBinary nodes is always determined automatically.
Together these changes make the code considerably cleaner.
Note that the code for constant folding for array indexing is actually
never hit because constant folding array constructors is still
intentionally disabled in the code.

Revert "Cover vector dynamic indexing case in SplitSequenceOperator"
This CL was causing inverted rendering in a WebGL application.
This reverts commit 7da9850643f55335a13a4663d226c73d0ac4d3b1.
Vectors or matrices that are dynamically indexed as a part of an
l-value generate new statements in the RemoveDynamicIndexing AST
transformation step. SplitSequenceOperator needs to detect this case
and split the sequence operator before statements are generated from
its operands to ensure the correct order of execution.

Remove dynamic indexing of matrices and vectors in HLSL
Re-re-relanding after clang warning fix.
Re-re-landing with fix to setting qualifiers on generated nodes. The
previous version failed when a uniform was indexed, because it would
set the uniform qualifier on some of the generated nodes and that
interfered with the operation of UniformsHLSL.
Re-landing after fixing D3D9 specific issues.
HLSL doesn't support dynamic indexing of matrices and vectors, so replace
that with helper functions that unroll dynamic indexing into switch/case
and static indexing.
Both the indexed vector/matrix expression and the index may have side
effects, and these will be evaluated correctly. If necessary, index
expressions that have side effects will be written to a temporary
variable that will replace the index.
Besides dEQP tests, this change is tested by a WebGL 2 conformance test.
In the case that a dynamic index is out-of-range, the base ESSL 3.00 spec
allows undefined behavior. KHR_robust_buffer_access_behavior adds the
requirement that program termination should not occur and that
out-of-range reads must return either a value from the active program's
memory or zero, and out-of-range writes should only affect the active
program's memory or do nothing. This patch clamps out-of-range indices so
that either the first or last item of the matrix/vector is accessed.
The code is not transformed in case the it fits within the limited subset
of ESSL 1.00 given in Appendix A of the spec. If the code isn't within
the restricted subset, even ESSL 1.00 shaders may require this
workaround.
