[X86] X86 trace JIT compiler support
This patch provides a fully functional x86 trace JIT compiler for Dalvik
VM. It is built on top of the existing x86 fast interpreter
with bug fixes and needed extension to support trace JIT interface. The
x86 trace JIT code generator was developed independent of the existing
template-based code generator and thus does not share exactly the same
infrastructure. Included in this patch are:
* Deprecated and removed the x86-atom fast interpreter that is no
longer functional since ICS.
* Augmented x86 fast interpreter to provide interfaces for x86 trace JIT
compiler.
* Added x86 trace JIT code generator with full JDWP debugging support.
* Method JIT and self-verification mode are not supported.
The x86 code generator uses the x86 instruction encoder/decoder library
from the Apache Harmony project. Additional wrapper extension and bug
fixes were added to support the x86 trace JIT code generator. The x86
instruction encoder/decoder is embedded inside the x86 code generator
under the libenc subdirectory.

Fix single-stepping resume mode in the interpreter.
(cherry-picked from master)
When a resume attempt is cancelled due to other pending request make sure
the old native resume PC is cleared. Otherwise the JIT code cache may be

Also fix a code bloat problem where single-step count is not set properly

Interpreter/Debugger fix #4479968
This one was tricky to track down. The underlying problem arose
with the consolidation of InterpState with Thread. Rather than
having a state structure for each instance of the interpreter, we
moved to a model that had a single thread-local struct shared by all
interpreter instances running on that thread. A portion of interpreter
state can't be shared - and thus was saved and restored on nested
invocations of the interpreter.
The bug here was that the storage for method return values was not
included in the state that needed save/retore. In normal operation,
it doesn't need to be saved - that storage isn't live across an
invoke that could trigger a nested interpreter activation. However,
when debugging, the debugger itself may hijack threads and create
new interpreter instances for its own purposed - and there is a small
window in which live retval can be trashed.
The fix is simply to move retval into the InterpSave struct.

Another single-stepping fix in JIT self-verification mode.
The counted single stepping check should be based on the
kSubModeCountedStep submode instead.
Also since the NPC value is cleared when exceptions are thrown, we can
single-step instructions that can throw as well.

InterpBreak cleanup (part 1)
Moved the suspend count variables from the interpBreak structure. These
are already protected by a mutex, and we need the space in interpBreak
for additional subMode flags. This CL just does the move and expands
