Propagating them looks a bit silly, because the arguments are unused. I
think this problem mainly occurs in constructors, which the dummy
argument obfuscator doesn't touch.

The aim of this change is to ensure that the automatically chosen class,
field and method names stay as similar as possible between runs.

This change paves the way to feed the NameMap into the TypedRemapper,
such that refactored names (and static member movements) are preserved
across deobfuscator runs.

We don't need to track the class version and maxStack value: the
Library::remap will already have access to them (and always needs to, as
it has to fiddle with {Class,Field,Method}Nodes to actually move the
field).

My rough plan for combining static scrambling and remapping is to split
Library::remap into three passes:
* Remove static methods, fields and initializers from the library,
storing them in a temporary location.
* Pass all classes through ClassNodeRemapper, as we do now.
* Add static methods, fields and initializers to their new classes,
remapping as we do so.
This ensures a ClassNode is never in a state where it has a mixture of
remapped and non-remapped fields, methods or instructions. This is
important to ensure no conflicts can occur when we use the refactored
names from the NameMap, rather than the auto-generated names.
It means TypedRemapper needs the ability to provide the instructions
that make up a field's initializer, such that Library::remap can move
these instructions to a different InsnList. The new getFieldInitializer
method and FieldInitializer type support this.

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

This reverts commit b6bba95435.
Although this code is more complicated, it allows us to control the
destination class for fields individually (rather than an entire set at
a time). This is a requirement for name mapping.
