x86: Don't change mode for XOR in ix86_expand_ternlog
There is no need to change mode for XOR in ix86_expand_ternlog now.
Whatever reasons for it in the first place no longer exist. Tested
on x86-64 with -m32. There are no regressions.
* config/i386/i386-expand.cc (ix86_expand_ternlog): Don't change
mode for XOR.
