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.

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.

Simplify loop conditions so that they won't generate statements
Introduce an AST traverser that can move the evaluation of certain
types of loop conditions and loop expressions inside the loop. This
way subsequent AST transformations don't have to worry about cases
where they have to insert new statements to implement a loop condition
or expression.
This includes the revert of "Unfold short-circuiting operators in loop
conditions correctly". The new traverser covers the loop cases that
used to be handled in UnfoldShortCircuitToIf.
