x86: Add -z isa-level-report=[none|all|needed|used]

Browse Source 
Add -z isa-level-report=[none|all|needed|used] to the x86 ELF linker to
report needed and used x86-64 ISA levels.

	* elf-linker-x86.h (elf_x86_isa_level_report): New.
	(elf_linker_x86_params): Add isa_level_report.
	* elfxx-x86.c (report_isa_level): New.
	(_bfd_x86_elf_link_setup_gnu_properties): Check
	-z isa-level-report=[none|all|needed|used] to report needed and
	used x86-64 ISA level.

* Add -z isa-level-report=[none|all|needed|used] to the x86 ELF linker
to report needed and used x86-64 ISA levels.
* Add --rosegment option which changes the -z separate-code option so that
only one read-only segment is created (instead of two). (The option name
is misleading, but it matches the name used by LLD and GOLD).
