Review: GenerateNativeHeader for mac

[Erik Joelsson]

When converting the mac build to build-infra, a bunch of files needed 
the new annotation GenerateNativeHeader. In order to still compile in 
the old build, langtools had to be added to the classpath in the ant 
script compiling those classes, since they were compiled by the bootjdk 
javac rather than the bootstrap javac.

In addition to this some of the java code used to generate java classes 
have been modified to sort the output to make the generated classes 
deterministic. This makes comparing the new and old build easier. 
Previously the order of methods in these generated classes were random 
on hashvalues.
