Subject: [patch] conditionally declare bswap functions depending on target

The target I am working on is 16-bit target and cannot support 64- bit data types (DI mode).
How about conditionally declare the function?
#if LONG_LONG_TYPE_SIZE > 32
extern DItype __bswapdi2 (DItype);
#endif

So, I finally got around to this patch. While I was at it I went ahead and check SImode as well.

Tested on mips64vr-elf and x86-darwin.

OK?

	__bswapdi2.
