DF_RD->gen.
* df.h (df_changeable_flags.DF_RD_NO_TRIM): Deleted
(df_rd_bb_info.expanded_lr_out): Deleted
* loop_invariant.c (find_defs): Deleted DF_RD_NO_TRIM flag.

(df_rd_free_bb_info, df_rd_alloc, df_rd_confluence_n,
df_rd_bb_local_compute, df_rd_transfer_function, df_rd_free):
Removed code to allocate, initialize or free expanded_lr_out.

understandable.
(df_rd_confluence_n): Removed code to no apply invalidate_by_call
sets if the sets are being trimmed.
