convert elf_link_hash macros to inline functions

Involves a bit of editing as we now need to be more precise in pointer
types.

bfd/
	* elf-bfd.h (is_elf_hash_table): Convert macro to inline function.
	(elf_link_hash_lookup, elf_link_hash_traverse): Likewise.
	(elf_hash_table, elf_hash_table_id): Likewise.
	* elf32-arm.c (elf32_arm_setup_section_lists): Delete redundant
	is_elf_hash_table check.
	* elf32-csky.c (elf32_csky_setup_section_lists): Likewise.
	* elf32-hppa.c (clobber_millicode_symbols): Correct param types.
