i386.md (bswap<mode>2): Macroize expander from bswap{si,di}2 using SWI48 mode iterator. 

* config/i386/i386.md (bswap<mode>2): Macroize expander from
	bswap{si,di}2 using SWI48 mode iterator.
	(*bswap<mode>2_movbe): Macroize insn from *bswap{si,di}_movbe using
	SWI48 mode iterator.  Set type attribute of bswap insn to bitmanip,
	set modrm attribute of bswap insn to 0 and remove length attribute.
	(*bswap<mode>2_1): Macroize insn from *bswap{si,di}_1 using SWI48 mode
	iterator.  Set type attribute to bitmanip, set modrm attribute to 0,
	set mode attribute to <MODE> and remove length attribute.
