i965/fs: Fix fs_inst::regs_read() for uniform pull constant loads
Previously, fs_inst::regs_read() fell back to depending on the register width for the second source. This isn't really correct since it isn't a SIMD8 value at all, but a SIMD4x2 value. This commit changes it to explicitly be always one register. v2: Use mlen for determining the number of registers read Reviewed-by: Iago Toral Quiroga <[email protected]> Acked-by: Francisco Jerez <[email protected]>
