rs6000: Simplify some code with rs6000_builtin_is_supported

In function rs6000_init_builtins, there is a oversight that
in one target debugging hunk with TARGET_DEBUG_BUILTIN we
missed to handle enum bif_enable ENB_CELL.  It's easy to
fix it by adding another if case.  But considering the long
term maintainability, this patch updates it with the existing
function rs6000_builtin_is_supported, which centralizes the
related conditions for different enum bif_enable, we only
need to update that function once some condition needs to
be changed later.  This also simplifies another usage in
function rs6000_expand_builtin.

gcc/ChangeLog:

	* config/rs6000/rs6000-builtin.cc (rs6000_init_builtins): Fix the
	oversight on ENB_CELL by simplifying with rs6000_builtin_is_supported.
	(rs6000_expand_builtin): Simplify with rs6000_builtin_is_supported.
