93100e57b2 Improve how the instance-of + if-eqz/if-nez type propagation works 
We now perform the type propagation while analyzing the if-eqz/if-nez
instruction. Additionally, AnalyzedInstruction.setsRegister now has
special case logic to check for this case, so we don't incorrectly
propagate the original type past the if-eqz/if-nez

da58cc8991 Only use the instance-of/if-eqz type info if we're getting more information 
We should only use the type info from an instance-of/if-eqz combo if we're
going from an interface to a class, or going from a class to a subtype
of that class -- otherwise, we're actually losing information.

398630dde5 Infer the register type based on the result of an instance-of instruction 
In oat files, it's possible that a check-cast is removed based on the
register being provably of the type being cast to, based on the result
of an instance-of check.

Supporting this in general would require more sophisticated static analysis
than is currently done. Instead, this adds a special-case specifically
for the case of an instance-of followed immediately by an if-eqz

827e2db34d Add support for normalizing virtual methods 
This is useful, for example, when comparing the result of deodexing with
the original dex file, to remove the "false" differences caused by the
different potential ways to reference a given virtual method.

c456c55c40 Make smali respect order of implements 
Previously smali would reorder implements directives to be
alphabetical in the dex file. In the Java 8 Language the order of
interfaces may affect the order of initializer invocation when using
default methods. Therefore we will preserve this order in
smali/baksmai.

0f1e995099 Add the generated accessorTest to source control 
Some java compilers don't generate the synthetic accessor methods in the
way that the accessorTest is trying to test. So we build the test dex
file using a known-good compiler and check it in, ensuring the test is
always run using an appropriate dex file.

b76dee7ebd Don't assume dx is on-path. Rather, grab it from maven central 
The version of dx in maven central seems to be fairly old, but it works
well enough for our purposes.
