Post ISel, LDS variables are absolute values. Representing them as
such is simpler than the frame recalculation currently used to build assembler
tables from their addresses.

This is a precursor to lowering dynamic/external LDS accesses from non-kernel
functions. Machine function instances are not available in MCInstLower. The
metadata written on global variables does last until MC. No test changes as no
observable behaviour change.
