652: ASG refactor r=collinc97 a=Protryon
## Motivation
This PR makes the ASG more user friendly by using arenas instead of RefCell/Arc:
1. Impossible to leak the ASG by creating a circular strong reference chain
2. We don't need RefCell's everywhere to implement passes
663: Bug 625/fix negative fields not allowed r=collinc97 a=gluax
Resolves#625. Logic used to do so is in check if first character of string to convert is a negative sign. If so remove first character convert from string to field, and then negate it on the leo side. If first character wasn't a negative sign, do the same as before.
