i965: Only consider fixed_hw_reg in equals() if file is HW_REG/IMM.

Noticed when debugging things that lead to the next patch.

On G45 (and presumably ILK) this helps register coalescing:

total instructions in shared programs: 4077373 -> 4077340 (-0.00%)
instructions in affected programs:     43751 -> 43718 (-0.08%)
