Process 64-bit imm/disp only for 64-bit BFD
We only need to store 32-bit immediate in 64-bit and optimize 64-bit
displacement to 32-bit only for 64-bit BFD.
* config/tc-i386.c (optimize_imm): Store 32-bit immediate in
64-bit only for 64-bit BFD
(optimize_disp): Optimize 64-bit displacement to 32-bit only
for 64-bit BFD.
