    [ld, testsuite] Always assemble those intermediate .o files used later
    
    ld/
    	* testsuite/ld-plugin/lto.exp (lto_link_elf_tests): Move "Compile 7",
    	"Compile 8a", "Compile 8b"...
    	(lto_compile_elf_tests): ...to here.  Always run these tests.
    	(lto_run_elf_tests): Move "LTO 7"...
    	(lto_run_elf_shared_tests): ...to here.  Restrict these tests on
    	environment where share library is supported.
    
    (cherry picked from commit 077c11e8679ea7fb4fae977327786fea8353132f)
