[x86_64 PATCH] Add rotl64ti2_doubleword pattern to i386.md

This patch adds rot[lr]64ti2_doubleword patterns to the x86_64 backend, to move splitting of 128-bit TImode rotates by 64 bits after reload, matching what we now do for 64-bit DImode rotations by 32 bits with -m32. In theory moving when this rotation is split should have little influence on code
