[Cpptool-develop] Progress on InlineTemp

[Andre B. <and...@gm...>]

There're just two things that are left to be done for the InlineTemp 
refactoring.
Both of them need an improvement in expression parsing I'm currently 
thinking
about. The two things are:
- detect assignments to a temporary variable
- find out if the initializer expression consists of one or more 
elements (in case
   of more elements I need to add braces when inlining the expression)
For both things I need some more details on the operations in the 
expression.
I'm currently thinking of some ExpressionOperationMutator which splits 
an expression
into it's highest level operation. Unfortunatly this splitting isn't so 
easy since it needs
to know about all kinds of operators and their level.
we all known: "*a = 10;" splits into "*a" and "10".
The ExpressionOperationMutator can build upon the ExpressionMutator 
which has the
tokenizer implemented.
Another question is, how to present this in the AST. My suggestion would 
be to keep that
"expression"-ASTNode and add different Operation-Properties.

I'm open for discussion, since this seems to be a thing that will 
influence many other
refactoring and codegen functionality.
