X86: Use memory to do array range checks

Currently, an HBoundsCheck is fed by an HArrayLength, causing a load of
the array length, followed by a register compare.

Avoid the load when we can by comparing directly with the array length
in memory.  Implement this by marking the HArrayLength as 'emitted at
use site', and then generating the code in the HBoundsCheck.

Only do this replacement when we are the only user of the ArrayLength
and it isn't visible to the environment.

Handle the special case where the array is 'null' and where an implicit
null check can't be eliminated.

This code moves the load of the length to the slow code for the failed
check, which is what we want.

ART: Add Mterp export pc poison testing mode

One of the optimizations of the Mterp assembly interpreter is
that it attempts to limit the number of times it updates the saved
dex_pc_ value stored in the shadow frame.  Instead, it maintains
a pointer to the current dex instruction in a dedicated register.

However, whenever execution flow exits the immediate mterp
environment and some other part of the runtime needs to know the
current dex pc (for example - exception throws), mterp must
save - or "export" the dex_pc back into it's home location in
the shadow frame.

Forgetting to do this is a typical bug when developing mterp
instruction handlers.  And, the failures show up in odd and
sometimes hard to track down ways.  This CL adds a testing mode
that poisons the saved dex_pc prior to each instruction
interpretation.  Thus, if any individual handler neglects to
properly export the current dex pc and then goes on to use it
we'll segfault out with an identifiable fault address: 0xdead00ff.

TEST: test-art-target (Nexus 5x, Nexus 6p), test-art-host.  Verified
expected failure by artificially neglecting an EXPORT_PC.
