The AArch32 VIXL-based code generator has been the default
ARM code generator in ART for some time now. The old ARM
code generator does not compile anymore; retiring it.
Test: test.py
Bug: 63316036

Test: test-art-host, test-art-target.

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.

Rationale:
This CL adds the concept of vectorizing intrinsics
to the ART vectorizer. More can follow (MIN, MAX, etc).

Rationale:
Make SIMD great again with a retargetable and easily extendable vectorizer.
Provides a full x86/x86_64 and a proof-of-concept ARM implementation. Sample
improvement (without any perf tuning yet) for Linpack on x86 is about 20% to 50%.
