Bug Description

Stack frames containing simd-packs or simd-pack-256s in either registers or stack locations cannot be inspected with SLDB. When attempting to list the local variables and their values in the SLIME debugger, the function SUB-ACCESS-DEBUG-VAR-SLOT signals an error because it encounters an SC number that is not handled by its ecase expression.

It seems debugger support for those SC numbers simply hasn't been written yet. The attached patch implements the missing functionality.

This is on SBCL 2.1.8 (and older versions), and on an x86-64 machine with AVX2.
