Fix issue with obsolete methods and const-method-handle

We were incorrectly using the non-obsolete version of the method to
search for the target of const-method-handle instructions. This meant
that obsolete methods would see the wrong method-handle or crash.

Since no java code (currently) compiles to dex code using
'const-method-handle' we needed to use ASM to construct the test
class.
