i.e. remove the condition that there must be an LVT entry. Such
temporary `Ref`s can be created, for example, by the JVM_IR backend
if a lambda inlined at an IR level (e.g. argument to `assert`/`Array`)
is the target of a non-local return from a function inlined at bytecode
level (e.g. `run`):
IntArray(n) { i ->
intOrNull?.let { return@IntArray it }
someInt
}
->
val `tmp$0` = IntArray(n)
for (i in 0 until `tmp$0`.size) {
var `tmp$1`: Int
do {
intOrNull?.let {
`tmp$1` = it // causes `tmp$1` to become an IntRef
break
}
`tmp$1` = someInt
} while (false)
`tmp$0`[i] = `tmp$1`
}
The number of initializations of the `value` field before the live range
begins does not really matter so long as we insert a write of a default
value to the local if there were none.
All bytecode text tests are run with stdlib in the classpath and only
for JVM backend, therefore directives WITH_RUNTIME, TARGET_BACKEND,
IGNORE_BACKEND are not needed
- Turn some const conditions into non-const conditions
- Make sure inlined const values are used where required
(otherwise they are eliminated by POP backward propagation)
