Add basic recognition of new EM_ ELF machine numbers.

include	* elf/common.h (EM_LANAI): New machine number.
	(EM_BPF): Likewise.
	(EM_WEBASSEMBLY): Likewise.
	Move low value, deprecated, numbers to their numerical
	equivalents.

binutils * readelf.c (get_machine_name): Rearrange switch table in order of
	increasing machine number.  Add missing entries.
