 Log message:
 	PR optimization/6627
 	* toplev.c (force_align_functions_log): New global variable.
 	* flags.h (force_align_functions_log): Add extern prototype.
 	* varasm.c (assemble_start_function): Use it to force minimum
 	function alignment.
 	* config/i386/i386.h (FUNCTION_BOUNDARY): Set the correct
 	minimum function alignment to one byte.
 	(TARGET_PTRMEMFUNC_VBIT_LOCATION): Store the virtual bit in
 	the least significant bit of vtable member function pointers.
 	* tree.h (enum ptrmemfunc_vbit_where_t): Move definition to
 	here from cp/cp-tree.h.
 	
 	* cp/cp-tree.h (enum ptrmemfunc_vbit_where_t): Delete definition
 	from here, and move it to tree.h.
 	* cp/decl.c (cxx_init_decl_processing): If storing the vbit
 	in function pointers, ensure that force_align_functions_log
 	is atleast one.
 	
 	* java/lang.c (java_init): If storing the vbit in function
 	pointers, ensure that force_align_functions_log is atleast
 	one to aid compatability with g++ vtables.
