Convert __builtin_expect to __glibc_(un)likely throughout elf/.zack/elf-builtin-expect-conversion
In the previous patch I didn't change a use of __builtin_expect to __glibc_(un)likely that happened to be right next to the code I was actually working on; Andreas asked why not, and I said that there were a bunch more uses of __builtin_expect in that file and I would convert them all in a separate patch. This is that patch, converting all of elf/. I would appreciate someone checking over this patch very carefully indeed. In a whole bunch of places, __builtin_expect was used in a way that did not map mechanically to the newer convention. The test suite caught one mistake; I'm not confident I didn't make any more. Writing this patch gave me a deeper appreciation for why we _want_ to switch to __glibc_(un)likely, but also for how difficult it can be. I now think that people should _not_ be asked to change existing uses of __builtin_expect in a patch whose purpose is something else. * elf/dl-addr.c, elf/dl-cache.c, elf/dl-close.c, elf/dl-deps.c * elf/dl-environ.c, elf/dl-error-skeleton.c, elf/dl-fini.c * elf/dl-fptr.c, elf/dl-init.c, elf/dl-libc.c, elf/dl-minimal.c * elf/dl-open.c, elf/dl-reloc.c, elf/dl-runtime.c * elf/dl-sysdep.c, elf/dl-tls.c, elf/dl-version.c, elf/ldconfig.c * elf/rtld.c: Replace __builtin_expect with __glibc_likely or __glibc_unlikely, as appropriate, throughout.
