More precise values in Analyzer

Hi,

Im trying to use ASM in a Java-to-LLVM translator project.  In short, I'm using
the Analyzer and a custom version of Value to (attempt to) extract a SSA form
of the Java bytecode.

The problem I am having is that some of the origins of the values are not
precise enough.  For instance, at present, it seems impossible to track where
some of the values originally came from - Analyzer.analyze just calls
Interpreter.newValue(...) for uninitialized values, parameters, the this
reference, etc.

What do you recommend?

Would I be able to get a patch through that gives the Interpreter room to
distinguish between these?  I propose adding Interpreter.newParameter(int
index, Type type), Interpreter.newReturnValue(Type type),
Interpreter.newThisReference(Type type), and Interpreter.newUninitialized().

FYI, I am using the stable 3.3 version - but the nightly SVN seems to have the
same problem.

Sincerely,

Joshua Warner
