assign true, jump, assign false now only emit when x= boolexpr_e

This must be done for every other parser rule that has expr in r value. Also jump labels all fixed for aforementioned cases.
Fixed case: x = a and b and false; Removed pesky jumps.
"and" will now reuse temp vars

still has extra emmit in x = a and b and c;
"or" implemented

still has extra emmit in x = a and b and c;
motherfucking not is done. 'and' and 'or' also completely donenene!

moving to relops yo!
relational operators done!
fixed relops for {(a relop b) relop c;} and {a relop (b relop c);}

{x=a and not b;} could be done without the 4 more emits
