[i386] Call force_reg unconditionally.
There is no point to check RTXes before calling force_reg,
force_reg checks for REG RTX by itself.

gcc/
* config/i386/i386.md (*btr<mode>_1): Call force_reg unconditionally.
(conditional moves with memory inputs splitters): Ditto.
* config/i386/sse.md (one_cmpl<mode>2): Simplify.
