KT-12275 Add JS optimization that transforms the following code
...
```
do {
X
if (B) break;
} while (A)
```
to
```
do {
X
} while (!B && A)
```
Add inversion that takes boolean expression and applies negation to it, simplifying if possible (like !!a => a).

JS/Inlining: fix bug in temporary assignment elimination which causes excess removal of assignment statement. When there is a set of temporary variables that receive same value in different execution branches, remove them carefully so that at least one (and, preferably, at most) remains in each branch.
