Emit CFI for x86 & x86_64 JNI compiler.
Now for host-side x86 & x86_64 ART, we are able to get complete stacktrace with even mixed C/C++ & Java stack frames.
Testing:
1. art/test/run-test --host --gdb [--64] --no-relocate 005
2. In gdb, run 'b art::Class_classForName' which is implementation of a Java native method, then 'r'
3. In gdb, run 'bt'. You should see stack frames down to main()
