[Bug rtl-optimization/29854] New: reload_combine looses track of uses

["amylaar at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

When reload_combine replaces a register with a sum of
another register ('base') and a constant, it fails to
note the new uses of the base.  Thus, when it later
replaces the base, thew new uses won't be updated.

A patch is here:
