[i965] short immediate values must be replicated to both halves of the dword

Browse source 
The 32-bit immediate value in the i965 instruction word must contain two
copies of any 16-bit constants. brw_imm_uw and brw_imm_w just needed to
copy the value into both halves of the immediate value instruction field.
