i386.c (processor_target_table): Increase maximum skip from 7 byte to 10 byte for Pentium Pro... 

2007-06-21  H.J. Lu  <hongjiu.lu@intel.com>

	* config/i386/i386.c (processor_target_table): Increase maximum
	skip from 7 byte to 10 byte for Pentium Pro, Core 2 Duo and
	default 64bit.

	* config/i386/linux.h (ASM_OUTPUT_MAX_SKIP_ALIGN): Ensure 8
	byte alignment if > 8 byte alignment is preferred.
	* config/i386/x86-64.h (ASM_OUTPUT_MAX_SKIP_ALIGN): Likewise.
