Split ternary node class from TIntermSelection
Ternary operator nodes are typed parts of expressions, they always
have two children and the children are also guaranteed to be
TIntermTyped. "If" selection nodes can't be a part of an expression,
they can have either one or two children and the children are code
blocks. Due to all of these differences it makes sense to store these
using two different AST node classes.

Fix splitting nested sequence operators
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.

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.

Split sequence operator when necessary
Split sequence operators if some of their operands generate statements
in subsequent AST transformations to guarantee the right order of
execution. For now, this is supported for expressions that return
arrays and unfolded short-circuiting operators, which is enough to get
WebGL 2 tests passing. A trickier corner case with dynamic indexing of
vectors as an l-value is left to be addressed later.
