This breaks the build for x86_64 targets. This is because on target the libvixl is not included as a
library for the libart.so target build. The build of non-x86_64 targets only works because the
compilers removes the dead-code that contains the libvixl symbols.

ART: Compress LengthPrefixedArray on 32-bit targets.
Previously, the LengthPrefixedArray<ArtMethod> on 32-bit
targets contained a 64-bit length field followed by the
ArtMethod elements with size only a multiple of 4, not 8.
Consequently, an odd-length array broke the alignment for
the following array which would have the 64-bit length
placed at an unaligned address.
To fix that, we make the length field 32-bit and explicitly
pass the alignment information to the LengthPrefixedArray.
This also makes the 32-bit boot image a bit smaller.
On Nexus 5, AOSP, ToT, the field section is 11528B smaller
and the method section is 21036B smaller. 64-bit targets
should see the same savings for the field section but no
difference for the methods section.

Intrinsics recognizer returns kNone for MIPS, MIPS64 instruction sets
Since no intrinsics are implemented in MIPS or MIPS64, the intrinsics
recognizer now does not mark methods as being intrinsified if the
current instruction set is either MIPS or MIPS64.

Small optimization improvements.
- Tune CanBeNull for HBoundType.
- Remove LoadClass when we know the class is loaded.

Wait for GC to finish in ThreadList::~ThreadList
Added a DisableGC to the heap instead of using the runtime shutdown
boolean. The runtime shutting down boolean is set to true before the
non daemon threads have exited. These threads may still be doing
allocations and we don't want to throw OOME if unnecessary.

Add support to indicate whether intrinsics require an environment
A structural change to indicate whether a given intrinsic requires
access to an environment. I added a field to HInvoke objects to indicate
if they need an environment whose default value is true and is only updated
if an intrinsic is marked as not requiring an environment. At this point
there is no functional change, as all intrinsics are marked as requiring
an environment. This change adds the structure for future inliner work
which will allow us to inline more intrinsified calls.

ART: Change UninitializedThis tracking in the verifier
Only relying on register types is error-prone. For example, we may
inadvertently reject correct code when the constructor terminates
abnormally.

Daemon threads may be trying to do allocations as the runtime is

This will be used by incoming architecture specific optimizations. The
dependencies must be conservative. When an HInstruction is created we

'ChangesGC' dependency must be set. We control at code-generation time
that HInstructions that can call have the 'ChangesGC' dependency
