enabling interleaved access loop vectorization
Is there a compile-time and/or potential runtime cost that makes
enableInterleavedAccessVectorization() default to 'false'?
I notice that this is set to true for ARM, AArch64, and PPC.
In particular, I'm wondering if there's a reason it's not enabled for x86
in relation to PR27881:

Hi Sanjay,
The feature was originally developed for ARM's VLDn/VSTn instructions
and then extended to AArch64 and PPC, but not x86/64 yet.
I believe Elena was working on that, but needed to get the
scatter/gather intrinsics working first. I j...
