Remove CALL_THREAD_FCT macro
This patch removes CALL_THREAD_FCT macro usage and its defition for x86. For 32 bits it usage is only for force 16 stack alignment, however stack is already explicit aligned in clone syscall. For 64 bits and x32 it just a function call and there is no need to code it with inline assembly. Checked on i686-linux-gnu, x86_64-linux-gnu, and x86_64-linux-gnu-x32. * nptl/pthread_create.c (START_THREAD_DEFN): Remove CALL_THREAD_FCT macro usage. * sysdeps/i386/nptl/tls.h (CALL_THREAD_FCT): Remove definition. * sysdeps/x86_64/nptl/tls.h (CALL_THREAD_FCT): Likewise. * sysdeps/x86_64/32/nptl/tls.h: Remove file.
