gas: Generate code for if statement
If statements are now working, the only exception is for the comparators
|| and && that will be addressed in a further commit. Checks tested:
fn main(): i32 {
let n: i32 = 11;
if (n == 11) {
if n != 12 {
if n < 12 {
if n <= 11 {
if n > 10 {
if n >= 11 {
return 42;
}
}
}
}
}
}
return n;
}
To compile the && and || a precedence issue must be addressed: they must
have the highest precedence, witch is not working now:
1 == 2 || 3 != 2
The or should be the higher level of the tree in the example above.
