Skip debug sections when estimating distances

Browse source 
Skip debug sections when estimating distances between output sections
since compressed_size is used to compress debug sections and debug
sections aren't excluded from distances between output sections.

bfd/

	PR ld/20006
	* elf64-x86-64.c (elf_x86_64_convert_load): Skip debug sections
	when estimating distances between output sections.

ld/

	PR ld/20006
	* testsuite/ld-elfvsb/elfvsb.exp (COMPRESS_LDFLAG): New.
	(visibility_run): Pass COMPRESS_LDFLAG to visibility_test on
	ELF targets.
