ART: ELF symbol table lookup is fixed
ELF loader could not find some symbols in the OAT's symbol table
(e.g. oatdata, oatexec).
There was a bug in the symbol hash table lookup: if a valid index of
a chain got greater or equal than the number of hash buckets then
the chain was cut off.
The fix is to compare the chain index with the chains array length
rather than with the number of buckets.

after phi nodes are inserted.
BBCombine also had issue in that it did not properly maintain the
instruction links. The logic has been updated to use utility methods.
SplitBlock has an issue with being called after extended instructions
are inserted. Namely, in the case in question, it was called after
SpecialMethodInliner was through and although it was doing semantically
correct thing, it was hitting dcheck due to the kMirOpNullCheck.

ART: Add div-zero check elimination to LVN/GVN
GVN has been updated to also consider div/rem zero check elimination.
This means that whenever a divisor is used in two sequential divisions,
the second division will surely not throw exception.
The algorithm has been updated to work on global level by considering
splits and merges. Obviously, if "div_zero" checked on one path but
not the other, at merge point consider that division has not been
eliminated.
One big deficiency of this algorithm is that it does not consider
literals in the divisor. Namely, in cases where the operand is a literal
or a constant (literal created by another bytecode), it does not mark as
divide by zero checked. However, in reality this is not an issue
because none of the backends generate the divide by zero check when
the constant value is known.

dex2oat: Pack likely-dirty objects together when generating the boot image
This introduces a new algorithm into image writer which "bins" objects
by how likely they are to be dirtied at runtime. Objects in the same bin
are placed contiguously in memory (i.e. into the same page). We try to
tune the bin selection based on how clean or how dirty the object will
likely be at runtime.
As-is, this saves about 150KB per-process (private-dirty pages) and 700KB in
zygote (shared-dirty).
There is still about 800KB of objects that are clean but located in
dirty pages, so with more analysis we can tune the bin selection and get
even more memory savings.

Prune image cache if the boot marker is still in place.
We place a marker in each isa cache dir and have the framework
delete it for us.
This seems like a convenient place to do it given all the other
dalvik-cache related code that hooks in here, and also because
this is the first point where we try to access the cache.
TODO: Add a timeout to the (higher level) zygote code to correctly
kill the surviving zygote if one of them never comes up.

ART: X86Mir2Lir::OpRegRegReg should expect kOpMul for r_dest == r_src2 case
OpRegRegReg in case of r_dest == r_src2 does not expect kOpMul as valid operation.
This provokes abort compiling instruction like "mul-int v0, v1, v0" if both
operands are arriving in registers.
The fix is to expect kOpMul as comutative operation.

JDWP: only deoptimize when it is required
We don't need to deoptimize anything when we forced the use of the
interpreter (-Xint). In this case, no compiled code is executed
(except native methods which are not concerned by deoptimization).
Therefore we even don't need to enable/disable deoptimization support
in instrumentation.
We also don't need to deoptimize a method that hasn't been compiled.
Since it will run with interpreter, there is no point deoptimizing
it. However this method may be inlined in a compiled caller method
so we still need to deoptimize everything in this case.
This CL updates breakpoint support by storing the required kind of
deoptimization for a particular method. There are 3 cases:
- kNothing: the method does not require deoptimization.
- kSelectiveDeoptimization: the method needs to be deoptimized.
- kFullDeoptimization: we must deoptimize everythinig.
When uninstalling a breakpoint, we need to do the reverse operation.
Also fixes the SanityCheckExistingBreakpoints function to control
breakpoints related to the given method only and adds extra verbose
logs when choosing the appropriate deoptimization kind.

Quick compiler: fix x86 special identity
The Quick compiler recognizes and specially handles a set of
small methods - including those that simply return one of their
arguments. For x86, special identity was broken if the returned
argument was a double that was passed half in register and half
in memory.
