IMPALA-9690 addendum: Add a legacy AVX mode
Impala 4 introduced a requirement that x86_64 machines
support AVX2. This adds a startup parameter
enable_legacy_avx_support that relaxes the AVX2 requirement
to require only AVX. By default, enable_legacy_avx_support
is false. enable_legacy_avx_support will be removed in a
future release, but it seems like a sensible way to support
older machines for now.
Testing:
- Ran with enable_legacy_avx_support on a pool of machines
that includes machines without AVX2
- Ran a core job on a machine with AVX2
