i965/fs: Recalculate live intervals in calculate_register_pressure().

Otherwise calling dump_instructions() after declaring a new fs_reg would
segfault when calculate_register_pressure()'s loop over reg walked off
the end of the virtual_grf_start[] array that calculate_live_intervals()
would have reallocated for you, if it had known there was a new
register.
