reload1.c (reload): Make all entries in reg_equiv_memory_loc unshared.
* reload1.c (reload): Make all entries in reg_equiv_memory_loc
unshared.
* reload.c (make_memloc): Copy result if it is still
reg_equiv_memory_loc[regno] on return.
(subst_reloads) [ENABLE_CHECKING]: Check that none of
reg_equiv_constant, reg_equiv_memory_loc, reg_equiv_address and
reg_equiv_mem are modified by the substitutions.
