1. It is not passed as a parameter to Interpreter/Codegen, instead Codegen access it directly when necessary.
2. ClassNameHelper.reset method is removed as inherently thread unsafe and data that should be used during compilation of single script is stored in Codegen itself.
3. Instead of a special DefaultClassRepository null is used to indicate that generated classes should not be stored and JavaAdapter is modified to take ClassRepository as a parameter, not ClassNameHelper.

PreorderNodeIterator iter = new PreorderNodeIterator();
for (iter.start(tree); !iter.done(); iter.next()) {
Node node = iter.getCurrent();
...
}
instead of
PreorderNodeIterator iter = tree.getPreorderIterator();
Node node;
while ((node = iter.nextNode()) != null) {
}
to allow for more flexible usage and added PreorderNodeIterator.nextSkipSubtree to skip iteration of the last visited node subtree which allows to have simple code in Optimizer.buildStatementList when iterating over statements.

The bug caused by a missed check in StmtNodeIterator.nextNode for a possible null result of findFirstInterestingNode inside the search loop which made search to stop preliminary with non-empty stack.
The changes fixe this and integrate StmtNodeIterator into
Optimizer.buildStatementList as StmtNodeIterator was used only by
buildStatementList and the new version is simpler.

The reason for the bug was that omj/optimizer/Optimizer.java when optimizing code for this[name] (see GETELEM switch, line 665) assumed a number context for GETELEM index node unconditionally which is wrong.
The fix uses number context only if [] argument is known for sure to be a number.

The bug was caused by a double call to Codegen.addNumberConstant, the first
time correctly from Codegen.visitLiteral and the second time wrongfully from
the loop in emitConstantDudeInitializers where loop index should be used
instead of calling addNumberConstant. As addNumberConstant would return the
same index for same numbers, the bug surfaces only with NaN as
addNumberConstant does not recognizes already added NaN. The bug also visible
only with optimization set to 1 or higher since only then constant folding can
produce NaN literal.
The fix removes the second call to addNumberConstant and uses
ScriptRuntime.NaNobj for NaNs.

The reason for the bug is that emitDirectConstructor generates code to call
setPrototype twice instead of setPrototype/setParentScope pair during new JS
object construction. The fix replaces that setup by a single call to
BaseFunction.createObject which is used by Interpreter as well.

Integration of LineBuffer into TokenStream code which now uses a special buffer for unreading of several chars to follow SM more closely. In this way there is no problem with a possible backtracking of 3 chars on failed attempt to match <!-- at the last minus.
TokenStream is also modified to accept a string with a source directly which avoids the need to construct intermediate StringReader in Context and allows to remove DebugReader class which is replaced by a simple function to read all Reader data into string.

Codegen.visitRegularCall should not try to apply the simple call optimization
when firstArgDone is true indicating directly called function. The patch also
replaces generation of code to call new Object[0] by loading the
ScripRuntime.emptyArgs field.
