Remove global call sets: DF (EH edges)

The DF dense_invalidated_by_call and sparse_invalidated_by_call
sets are actually only used on EH edges, and so are more the set
of registers that are invalidated by a taken EH edge.  Under the
new order, that means that they describe eh_edge_abi.

gcc/
	* df-problems.c: Include regs.h and function-abi.h.
	(df_rd_problem_data): Rename sparse_invalidated_by_call to
	sparse_invalidated_by_eh and dense_invalidated_by_call to
	dense_invalidated_by_eh.
	(df_print_bb_index): Update accordingly.
	(df_rd_alloc, df_rd_start_dump, df_rd_confluence_n): Likewise.
	(df_lr_confluence_n): Use eh_edge_abi to get the set of registers
	that are clobbered by an EH edge.  Clobber partially-clobbered
	registers as well as fully-clobbered ones.
	(df_md_confluence_n): Likewise.
	(df_rd_local_compute): Likewise.  Update for changes to
	df_rd_problem_data.
	* df-scan.c (df_scan_start_dump): Use eh_edge_abi to get the set
	of registers that are clobbered by an EH edge.  Includde partially-
	clobbered registers as well as fully-clobbered ones.
