Exploited CHECK-START-{x,y,z} syntax.
Rationale:
Previous CL introduced new check syntax
to define multiple target architectures.
This CL exploits the new feature.

Make SIMD checker tests more robust.
Rationale:
With more and more peeling and cleanup loops coming up,
some of our checker tests were a bit fragile testing for
the first Phi occurrence. This CL fixes that. Also fixes
a few omissions found during the refactoring.

Improve sign and zero extension analysis.
Rationale:
This was needed to fix the regression introduced by
a prior type based cl. With the new type system ramping
up, however, this is actually more simplification (remove
the And recognition for example) than new code!

ART: Introduce Uint8 loads in compiled code.
Some vectorization patterns are not recognized anymore.
This shall be fixed later.

ART: Introduce Uint8 compiler data type.
This CL adds all the necessary codegen for the Uint8 type
but does not add code transformations that use that code.
Vectorization codegens are modified to use Uint8 as the
packed type when appropriate. The side effects are now
disconnected from the instruction's type after the graph has
been built to allow changing HArrayGet/H*FieldGet/HVecLoad
to use a type different from the underlying field or array.
Note: HArrayGet for String.charAt() is modified to have
no side effects whatsoever; Strings are immutable.

Test: testrunner.py --target --optimizing on Nexus 6P
Test: Nexus 6P boots.

ARM: ART Vectorizer (64-bit vectors).
Basic vectorization support with 64-bit vector length on ARM 32-bit
platforms (128-bit vectors require massive changes in register
allocator).

Implement halving add idiom (with checker tests).
Rationale:
First of several idioms that map to very efficient SIMD instructions.
Note that the is-zero-ext and is-sign-ext are general-purpose utilities
that will be widely used in the vectorizer to detect low precision
idioms, so expect that code to be shared with many CLs to come.
Test: test-art-host, test-art-target
