Actually, even though my patches introduce DWARF procedures for only

DWARF operations. Thinking more about it, it may be more sound to store
stack slot diffs instead of FUNCTION_DECL nodes in
dwarf_proc_decl_table.
Makes sense.
Done! (I repalced the dwarf_proc_decl_table hash table with a
dwarf_proc_stack_usage_map hash_map) Here's an update for the only
affected patch. Regtested again on x86_64-linux.
Hmm, can we generate the DWARF procedures during finalize_size_functions
to avoid the need for preserve_body?
