I'm going to try to minimise use of this (as per
https://github.com/google/guice/wiki/Avoid-Injecting-Closable-Resources).
For example, I'm going to inject a pooling DataSource rather than
Connection objects, as per the advice at the end of the page. However,
HikariCP's DataSource implementation is itself Closeable.

This already caught some cases of public members that should have been
private and one case where the inferred type was too specific.

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.

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.

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();`
