Don't use predicated vectorization by default.
This patch sets the traditional vectorization mode to be the default one; previously, if the target supported predicated vectorization (e.g. arm64 SVE), predicated vectorization was be tried for ALL loops. Motivation: this is a prerequisite for the further patches to enable mixed mode vectorization - when most of the loops are vectorized in traditional mode and some others - in predicated. A new env variable - ART_FORCE_TRY_PREDICATED_SIMD - is introduced to force-use the predicated mode; this could be set to true for testing purposes. Checker tests are adjusted accordingly - to also check the ART_FORCE_TRY_PREDICATED_SIMD variable. Test: test-art-target, test-art-host. Test: test-art-target with ART_FORCE_TRY_PREDICATED_SIMD=true. Original author: Artem Serov <Artem.Serov@linaro.org> Test: ./art/test/testrunner/testrunner.py --host --optimizing --jit Test: ./art/test/testrunner/testrunner.py --target --optimizing --jit (with ART_FORCE_TRY_PREDICATED_SIMD=true and without) Test: 661-checker-simd-cf-loops. Test: target tests on arm64 with SVE Change-Id: I57852f3777da6f86d615429d1a3c703cb87fbac8
