* compile time optimization:
int with doubles and strings
doubles with ints and strings
strings with ints and doubles
* bool with other types, more unary ops, float branch optimizer
* more tests
fixed bool to dbl compare
* output cleanup
more tests
* optimize string values in if statements, optimize ternary operator
* optimize elvis, addes missing files, code cleanup
* use array to keep unoptimized if branch in funcexpr tests
* missing include
* better readable testdata
* removed file
* optimize while and dowhile loops if predicate is a compile time known
value
* cleaner variant of loop optimization?
* added ConstantPredicateLoop Node used by the optimizer for constant loop
predicates
optimize repeat until loop
change tests to run the loops more then once to be sure they work
correctly
* test break/continue with label for constant-loop
* docs
