Ensure that binutils test names are unique.

binutils* testsuite/binutils-all/compress.exp: Rename second "objcopy
	zlib-gnu compress debug sections 3" test to "objcopy zlib-gabi
	compress debug sections 3" and use gabi object files instead
	of gnu object files.
	* testsuite/binutils-all/objcopy.exp: Add suffix to the names
	of the "ELF group" tests.
	* testsuite/binutils-all/readelf.exp (proc readelf_find_size):
	Add an iteration parameter and include it in the name of the
	test.  Update callers to include an iteration count.

gas	* testuite/gas/elf/group0a.d: Add extra details to the test
	name.
	* testuite/gas/elf/group0b.d: Likewise.
	* testuite/gas/elf/group1a.d: Likewise.
	* testuite/gas/elf/group1b.d: Likewise.
	* testuite/gas/elf/group0b.d: Likewise.
	* testuite/gas/elf/section9.d: Likewise.
	* testuite/gas/i386/ilp32/lns/lns-common-1.d: Likewise.
	* testuite/gas/i386/ilp32/lns/lns-duplicate-1.d: Likewise.

ld	* testuite/ld/ld-elf/audit.exp: Differentiate the names of the
	two "Run with shared with --audit" tests.
	* testuite/ld/ld-elf/compress.exp: Differentiate the zlib
	compressed debug output test names.
	* testuite/ld/ld-i386/tlspie1.d: Add extra details to the test
	name.
	* testuite/ld/ld-i386/tlspie2.d: Likewise.
	* testuite/ld/ld-size/size.exp: Add missing escapes to the end
	of lines in the size-3e test.
	* testuite/ld/ld-unique/unique.exp: Differentiate the names of
	the two "Checking unique PIC object" tests.
