Improve ix86_expand_fast_convert_bf_to_sf with new extendbfsf2_1.
After supporting extendbfsf2_1, ix86_expand_fast_convert_bf_to_sf can
be improved with pslld either.
CONST_INT_P is not handled since constant shift can be optimized off.
gcc/ChangeLog:
* config/i386/i386-expand.cc
(ix86_expand_fast_convert_bf_to_sf): Use extendbfsf2_1 for
nonimmediate operand.
gcc/testsuite/ChangeLog:
* gcc.target/i386/cbranchbf4.c: New test.
