Add -march=/-mtune=corei7-avx.

2010-12-06  H.J. Lu  <hongjiu.lu@intel.com>

	* config.gcc: Allow corei7-avx for --with-arch/--with-cpu.

	* config/i386/driver-i386.c (host_detect_local_cpu): Support
	Sandy Bridge.

	* config/i386/i386.c (override_options): Handle "corei7-avx".

	* doc/invoke.texi: Document corei7-avx.
