"not x" as a condition (if, while, until) is optimized into "x==0", this avoids calculating the value

add command line option 'optfloatx' to explicitly re-enable float expr optimization as this can increase code size significantly.
...
The output size of the various example programs using floating point, when not using this optimization, has been reduced significantly.
The resulting code runs a (tiny) bit slower though.

fix vardecl initialization value to not use stack eval anymore but separate assignment
...
(this causes the optimized assignment code gen to be used instead)
but some programs now end up larger in output size
