Auto-vectorizer generates 128-bit AVX insns by default for bdver1.
* config/i386/i386.opt (mprefer-avx128): Redefine the flag as a Mask option.
* config/i386/i386.h (ix86_tune_indices): Add X86_TUNE_AVX128_OPTIMAL entry.
(TARGET_AVX128_OPTIMAL): New definition.
* config/i386/i386.c (initial_ix86_tune_features): Initialize
X86_TUNE_AVX128_OPTIMAL entry.
(ix86_option_override_internal): Enable the generation
of the 128-bit instructions when TARGET_AVX128_OPTIMAL is set.
(ix86_preferred_simd_mode): Use TARGET_PREFER_AVX128.
(ix86_autovectorize_vector_sizes): Use TARGET_PREFER_AVX128.
