Change Resources field names to upper case

While the Resource class is technically not quite immutable (as it
contains a byte array), it's close enough as the array is only ever
read.

Add support for removing an argument whose local variable slot is used

This obviously doesn't work if the slot is loaded before something is
stored in it, but it does allow us to remove unused arguments whose slot
is re-used for another purpose.

Replace some primitive casts with widening/narrowing conversions
...
There are still some more contexts we can do this in - unary/binary
expressions and invocation contexts. I think Fernflower might handle the
former, but it doesn't handle the latter. Unfortunately, JavaParser's
method resolution code is still a bit too buggy to do the latter at the
moment.

Move literals to the RHS of an add/sub expression
...
The BinaryExprTransformer deals with this to an extent. However, it
requires multiple passes to do so. Adding support to AddSubTransformer
allows it to be done in a single pass.

Run IfElseTransformer until we reach a fixed point
...
It'd be nice if we could make it run a single pass (and there are
probably some improvements to reduce the number of required passes, as
I'm not convinced I'm running the transformations in a particularly
sensible order).
However, I think making it run in a single pass would be quite difficult
as some of the transformations need to propagate through else if chains
or nested if blocks. It's much easier to just run all the
transformations until they settle than fixing each individual
transformation.
