Fix FindFieldID to use class's classloader to find field type.

Also includes a test case, though the test case does not recreate
this exact issue because the attached native thread would need to
have a null context classloader.

Search for miranda methods in virtual methods instead of interface.

Also added tests that get miranda methods via reflection and jni.
Miranda methods can't be found via reflection, and have the interface
class as their declaring class when found via jni.

Fix NewLocalRef, NewGlobalRef to handle cleared weak globals.

We were not checking for null after decoding the reference, this
meant that we incorrectly created null weak global references instead
of returning null.

Fix stack overflow for mutual recursion.

There was an error where we would have a pc that was in the method
which generated the stack overflow. This didn't work however
because the stack overflow check was before we stored the method in
the stack. The result was that the stack overflow handler had a PC
which wasnt necessarily in the method at the top of the stack. This
is now fixed by always restoring the link register before branching
to the throw entrypoint.

Slight code size regression on ARM/Mips (unmeasured). Regression on ARM
is 4 bytes of code per stack overflow check. Some of this regression is
mitigated by having one less GC safepoint.

Also adds test case for StackOverflowError issue (from bdc).

Tests passing: ARM, X86, Mips
Phone booting: ARM

tools: use '/usr/bin/env python' instead of '/usr/bin/python'

* This is how it is done in other scripts in the AOSP tree, as
  '/usr/bin/python' may be python3 on some distros, which isn't
  supported yet.
