Use an appropriate data copier for the platform's bit width Dispatch on sb-vm:n-word-bits, though I think sbcl itself should probably define a system-area-double-float-copy bit-bash function. This also fixes a thinko, where only half of the times data was being copied, even on 64-bit platforms. Sheesh. Fixes #32
