i386.h (TARGET_64BIT): Define to constant if !TARGET_BI_ARCH

Browse Source 
* i386.h (TARGET_64BIT): Define to constant if !TARGET_BI_ARCH
	(CPP_CPU??_SIZE_TYPE): New.
	(CPP_CPU??_SPEC, CPP_CPUCOMMON_SPEC): Break out from...
	(CPP_CPU_SPEC): ... here; support choosing of CPU.
	(EXTRA_SPECS): Add cpp_cpu??, cpp_cpu??sizet, cpp_cpucommon.
	(MAX_LONG_TYPE_SIZE, MAX_BITS_PER_WORD): Define to 32 for 32bit-only
	compiler.
	* i386.c (override_options): Add sorry about not suported modes.
