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%)
helped: 52
HURT: 2
