Enabling JDK7+ bytecode requires stack map frames to be
emitted. ASM generates these automatically when given
a flag.

To enable faster single pass verification, java uses
stack map frames, which record stack contents at
just before the first instruction at a target branch.
The verifier easily tracks stack content within a basic
blocks.

ASM requires that you override getCommonSuperClass(t1, t2)
as its default implementation does classloading and does not
work for Clojure.

If you have code like so:
 (or (seq coll) ())
 :foo

immediately before :foo control flow merges with two different
types on the stack depending on the result of the or branch.
ASM calls getCommonSuperClass() to record into the stack map frame.

Luckily, because Clojure emits checkcasts conservatively before subsequent
calls, we do not have to provide maximally specific answers to
getCommonSuperClass(), instead we can return Object every time.

We may want to revisit this when LWorld value types happen, or when
generic specialization is available.
