Use max_align_t from <stddef.h>.
Now that we build with -std=gnu11 and can rely on a compiler providing max_align_t in <stddef.h>, we no longer need our own version libc_max_align_t. This patch removes it and replaces the single user with a use of max_align_t. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch for x86_64; for x86, I see some code reordering of no significance). * include/libc-internal.h (libc_max_align_t): Remove typedef. * include/scratch_buffer.h: Include <stddef.h> instead of <libc-internal.h>. (struct scratch_buffer): Use max_align_t instead of libc_max_align_t.
