History

Matthias Braun 9f6a38fc70 RegisterCoalescer: Do not remove IMPLICIT_DEFS if they are required for subranges.

The register coalescer used to remove implicit_defs when they are
covered by the main range anyway. With subreg liveness tracking we can't
do that anymore in places where the IMPLICIT_DEF is required as begin of
a subregister liverange.
