1a83d5a2d0 Propagate sideways conversions after an instance-of + if-eq/if-eqz 
Previously, we only propagated the conversion if it was a narrowing
conversion, to avoid problems that can occur with member access with
widening conversions.

However, it should be safe to do the conversion for a "sideways"
conversion - one that is neither widening or narrowing.

This can happen if we don't yet have full knowledge of the register types,
or, less likely, if the "true" branch is impossible to reach.

In the first case, we should get better type info as we continue to analyze
the method, and we'll revisit the conversion once we have better type info.

Or, if it really is an impossible conversion, we still want to propagate
the type from the instance-of to the true branch.

Now that dex files store an associated Opcodes instance, we don't need to
pass the api level around as much.

a6593575e7 Be more precise about narrowing after an instance-of 
Only do the additional narrowing when all predecessors of the instance-of
are equivalent move instructions.

e75f2b230a Ensure the ZipFile is closed in isZipFile() of ZipDexContainer 
When calling isZipFile() in ZipDexContainer, the ZipFile would remain open if
the file was in fact a zip file but the ZipFile object would then go out of
scope thus creating a resource leak. This ensures that the ZipFile is closed
by adding a finally clause containing a close call at the end of the try catch
block.

55c33ebb09 Add a placeholder ART version number / api level for aosp/master. 
Also make invoke-polymorphic conditional on this new art version.

This also fixes a bug where the version was being selected incorrectly
due to a parameter name that shadowed a local variable.

59256149f1 Add functionality for efficient multi-dex writing with DexPool 
This adds support to DexPool for mark()/reset(), which can be used to
"rollback" the last added class in case it caused a constant pool overflow.

This also adds a "DexWriter.hasOverflowed()" helper method to determine if
any of the size-constrained pools have overflowed.
