Make sure that only one sequence operator is split on one iteration
of SplitSequenceOperator. This prevents multiple successive PostVisit
calls to nested sequence operator nodes from adding duplicate nodes
to the AST. The sequence operators are split starting from the
outermost one to preserve execution order.

Note that the shader translator somewhat unexpectedly generates nested
sequence operators in the AST when there is a sequence operator with
more than two operands, so this bug ended up affecting shaders in the
wild. The code around parsing sequence operators could be clarified
separately.

GLSL function texelfetchoffset will be translated into texture.Load in
ANGLE. In D3D there is a note that When one or more of the coordinates
in Location exceeds the u, v, or w mipmap level dimensions of the
texture, Load returns zero in all components, but in glsl there is no
such restriction, which will cause the WebGL 2 dEQP test
deqp/functional/gles3/shadertexturefunction/texelfetchoffset.html fail
on Windows with Intel GPU.

Adapted from ExpandIntegerPowExpressions.cpp, this patch adds a
translation from texelFetchOffset into texelFetch to work around this
issue.

ANGLE has moved onto the Windows 10 SDK, and is using new compiler
features that aren't supported by the old Windows 8.1 toolchain. Support
for the 8.1 projects has been broken in master for some time now.

Since more and more developers are moving towards Windows 10, we
are going to take a snapshot of ANGLE that includes 8.1 support and
freeze it in a branch on github.com/microsoft/angle. If developers
wish to compile for use ANGLE in 8.1 apps then they should use that
branch going forward.

is never check for depth/stencil formats.
