[JS IR] Optimize pattern-matching of enums into comparing their ordinals
...
For this code:
```
enum class Season {
WINTER,
SPRING,
SUMMER,
AUTUMN
}
fun bar1(x : Season) : String {
return when (x) {
Season.WINTER, Season.SPRING -> "winter_spring"
Season.SUMMER -> "summer"
else -> "autumn"
}
}
```
previously we generated this:
```
function foo(x) {
var tmp0_subject = x;
return (tmp0_subject.equals(Season_WINTER_getInstance())
? true
: tmp0_subject.equals(Season_SPRING_getInstance()))
? 'winter_spring'
: tmp0_subject.equals(Season_SUMMER_getInstance())
? 'summer'
: 'autumn';
}
```
And now we generated this:
```
function bar2(x) {
var tmp0_subject = x;
var tmp0 = tmp0_subject._get_ordinal__0_k$();
var tmp;
switch (tmp0) {
case 0:
case 1:
tmp = 'winter_spring';
break;
case 2:
tmp = 'summer';
break;
case 3:
tmp = 'autumn';
break;
default:
noWhenBranchMatchedException();
break;
}
return tmp;
}
```

[FIR2IR] Introduce & use FirBuiltInsPackageFragment
...
Without this commit, JVM name mapping logic in BE does not work for FIR,
because FIR cannot use old BuiltInsPackageFragmentImpl descriptor.
In this commit we add our own implementation thus fixing
a pack of FIR black box tests.
