Fix a few functions which fall-through into an ENTRY macro. amd64 binaries now are free of double+-nop sequences (except for one assember nit in aes-586.pl).

This works better for both gcc and clang: gcc blocks overriding of internal calls, while clang permits inlining again. ok otto@ clang doesn't propagate attributes like "asm labels" and "visibility(hidden)" 2017-11-29T05:13:57Z guenther guenther@openbsd.org 2017-11-29T05:13:57Z urn:sha1:ea6088e7d368d53c49ebfdf4520275cec2f78f5b to builtins like mem{set,cpy,move} and __stack_smash_handler. So, when building with clang, instead mark those as protected visibility to get rid of the PLT relocations. We can't take the address of them then, but that's ok: it's a build-time error not a run-time error. ok kettenis@ Don't need .text before ENTRY(), also minor spacing cleanups 2017-08-19T18:24:06Z deraadt deraadt@openbsd.org 2017-08-19T18:24:06Z urn:sha1:f4882b558943284fa7fd7e3684b04b93801b3f8e
