1. Add libart/d.so to the list of additional public libraries
2. Fix java.library.path to include /system/lib(64)? for tests
   run by dalvikvm

Computation of dominance was broken in the presence of irreducible
loops because the algorithm assumed that back edges are always
dominated by their respective headers and a fix-point iteration is
therefore unnecessary.

This is not true for irreducible loops, forcing us to revisit their
loop headers and all dependent blocks. This patch adds a fix-point
iteration if a back edge not dominated by its header is found.

We used to always skip it as kIsDebugBuild was true for
libarttest.so and libarttestd.so.

No longer required since we unload native libraries.

(cherry picked from commit 64b0f0bf)

Previously both libarttest and libarttestd had debug enabled. This
made it hard to know which one was loaded (couldn't look at
kIsDebugBuild).

Fixes test 136 with ART_TEST_RUN_TEST_NDEBUG configuration.

* changes:
  Change test 136 to use dlopen
  Revert "Revert "(dl)Close native libraries on unload""

There is code that does
  new String(chararr, 0, chararr_count);
which under debuggable turns into a call into pNewEmptyString() plus a
call into pNewStringFromChars_CII().
Even though we currently don't patch return pc in a runtime method,
calling into pNewEmptyString() is special since it's hacked such
that it's acting as if the caller calls into the java method
StringFactory.newEmptyString() directly. So deoptimization can now
happen at the NewEmptyString site and the assert is triggered since
it's a new instance instead of an invoke instruction.

The fix relaxes the assert to allow the special case.

dlopen self to prevent the native libary being closed from
DestroyJavaVM. We need this since it is the library currently
executing code.

This reverts commit 0cf0dbd5.

Recent CL modified the (previously exponential) algorithm for
populating irreducible loops so as to not visit blocks multiple times.
However, the new condition for an early exit did not take into account
that it is not necessary to visit predecessors of the loop header.

The algorithm remains correct but does unnecessary work.

Dlclose native libraries when VM unloads a classloader. This
change is made to avoid leakage of adress space and RSS for
mapped but unreachable native libraries.

Otherwise, we may replace a dead loop phi with its incoming input.
This broke an assumption during liveness analysis in the presence
of irreducible loops.
