With GenBCode being the default and only supported backend for Java 8,
we can get rid of GenASM.
This commit also fixes/migrates/moves to pending/deletes tests which
depended on GenASM before.

`{i, l}div` and `{i, l}rem` throw an `ArithmeticException` if the
divisor is 0.
`arraylength` throws a `NullPointerException` on a null reference.
JVM Spec:
> The only integer operations that can throw an exception are the
> integer divide instructions (idiv and ldiv) and the integer
> remainder instructions (irem and lrem), which throw an
> ArithmeticException if the divisor is zero.
> The Java virtual machine's floating-point operators do not throw
> runtime exceptions
> If the arrayref is null, the arraylength instruction throws a
> NullPointerException.
I checked the other primitives in `ICode` to see if anything else
should be considered as live code.
Pure:
// jvm : {i, l, f, d}neg
case class Negation(kind: TypeKind) extends Primitive
// jvm : if{eq, ne, lt, ge, le, gt}, if{null, nonnull}
// if_icmp{eq, ne, lt, ge, le, gt}, if_acmp{eq,ne}
case class Test(op: TestOp, kind: TypeKind, zero: Boolean) extends Primitive
// jvm : lcmp, {f, d}cmp{l, g}
case class Comparison(op: ComparisonOp, kind: TypeKind) extends Primitive
Impure: {i, l}{div, rem}, otherwise pure
// jvm : {i, l, f, d}{add, sub, mul, div, rem}
case class Arithmetic(op: ArithmeticOp, kind: TypeKind) extends Primitive
Pure (overflow is silent, NaN.toInt is defined):
