for the non-optimizing compiler because if the new 'leader' quotation was not
compiled but some of the ones that it replaces were, then calls to the quotation
from contexts where they have to be compiled (eg, compiled if and dip) would no
longer work. Add a `jit-compile' primitive to compile quotations, and call it
as appropriate in `compress-quotations`.
instead of the Factor side passing the stack pointer as the first parameter, and having the VM save it to stack_chain->top, we instead have the Factor side save it. Eliminates a lot of crud in the VM
