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.

It's fairly similar to the ComplementTransformer, and translates
expressions like:
!a == !b => a == b
!a == b => a != b

calculateResolveType() is much more expensive than checking if an
expression is an integer literal, so swap the conditions around.

Some character literals are treated as integers by Fernflower, as the
complement operator always evaluates to an integer, even if its operand
is a character. This is fine, but ComplementTransformer removes some
complement transformers - leaving integer literals where Fernflower
would normally insert a character literal.
This transformer converts complemented integers to char literals in some
cases where it makes sense (it is difficult to perform this
transformation across every type of expression in JavaParser).

This commit improves support for simplifying a series of multiple
additions/subtractions and doing so in a single pass.

This commit makes two changes:
* Uses the is operator instead of the isXXX methods provided by
JavaParser, allowing smart casts to be used.
* Wraps unsupported expressions with a unary minus expression, rather
than throwing an exception.

Fixes a problem where `Constructor<?> var0 =
clazz.getDeclaredConstructor(); return var0.newInstance();` was transformed to
`Constructor<?> var0 = clazz.getDeclaredConstructor(); return
var0.getDeclaredConstructor().newInstance();`

As I'm splitting it up into smaller modules (e.g. compress and crypto) I
think util is a more appropriate name for the remainder.

This is a special case, so I've just hard-coded the GlEnum name and
value. Luckily its value is only used in the client in an OpenGL
context.
