Hiroshi Yamauchi [Wed, 13 Aug 2014 18:12:22 +0000 (11:12 -0700)]
More efficient stack walk in exception throwing.

In the exception handling code, we currently walk down the stack
twice, once to get the stack height which we use to compute frame IDs
(the bottom frame is zero), and once more to find the catch block to
jump to.

For a deep stack, this could result in very slow exception
handling. That is, if have a lot of finally or catch blocks that we
end up jumping to in a deep stack, we need to do a lot of
catch/rethrow chains. Since we'd need to walk down to the bottom each
time to compute frames IDs in each catch/rethrow, we'd need to walk
down O(N^2) frames at the worst case.

Instead of frames IDs ((the bottom frame is zero), we will use the
frame depth (the top frame is zero) and no longer need to walk down
the stack just to get the stack height. We walk down O(N) frames.

This was what was happening with
code.google.gson.functional.CircularReferenceTest. With this change,
the test run time went from ~120s down to ~3s on N5 and it no longer
crashes due to the thread suspension timeout.

ResolveMethod did not account correctly for the mutual exclusivity
of direct and static methods. In such a case we threw a NoSuchMethodError,
while the correct behavior is to throw an IncompatibleClassChangeError.

When the call stack does not have the three methods we expect,
the visitor will return a nullptr value.

Add a test to JniTest (and refactor the test a little for code reuse).

Add implicit checks for x86_64 architecture.

This combines the x86 and x86_64 fault handlers into one.  It also
merges in the change to the entrypoints for X86_64.

Replaces generic instruction length calculator with one that only
works with the specific instructions we use.
