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.
