rewrite_elf_program_header and want_p_paddr_set_to_zero
Layout in rewrite_elf_program_header is really done by lma, even if
program headers are going to have their p_paddr forced to zero. Thus
when not matching against an existing segment, don't try to use a
"vma" from elf_segment_map.
* elf.c (is_contained_by): Replace "bed" param with "use_vaddr".
(IS_SECTION_IN_INPUT_SEGMENT): Adjust is_contained_by call.
(rewrite_elf_program_header): Always match against lma in
calls to is_contained_by using new maps.
