target-mips: fix conditional moves off fp condition codes 

Conditional moves off fp condition codes were using the result of
get_fp_bit to isolate and test the relevant condition code.  However,
get_fp_bit returns the bit number of the condition code, not a
bitmask.  (Compare the use of get_fp_bit in gen_compute_branch1, for
instance.)

Fixed by shifting a bitmask into place using the result of get_fp_bit in
the relevant functions (gen_mov{ci,cf_s,cf_d,cf_ps}).
