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.
