Remove CALL_THREAD_FCT macro

Browse Source 
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.
