i965: Avoid explicit accumulator operands in SIMD16 mode on Gen7.

According to the BSpec ISA volume's "Accumulator Register" section:

"[DevIVB] SIMD16 execution on dwords is not allowed when accumulator is
 explicit source or destination operand."

Fixes piglit tests:
- fs-multiply-const-ivec4
- fs-multiply-const-uvec4
- fs-multiply-ivec4-const
- fs-multiply-uvec4-const
