Tune alignment for Intel Core i7

	* config/i386.h (TARGET_COREI7{_32,_64,}): New macros.
	(enum processor_type): Update comment.  Add entries for Core i7.
	* config/i386-c.c (ix86_target_macros_internal): Update.
	* config/i386.c (m_COREI7{_32,_64}): New macros.
	(m_GENERIC32, m_GENERIC64): Use generic tuning for Core i7.
	(processor_target_table): Tune alignment for Core i7.
	(ix86_option_override_internal): Use PROCESSOR_COREI7_*.

	* doc/invoke.texi: Document "corei7" option value.
