i965/fs: Invalidate live intervals when demoting uniforms to pull params.

Normally, nothing uses live intervals at this point, so this isn't
necessary.  However, dump_instructions() calculates them and uses them
to show register pressure.  So, calling dump_instructions() in this area
of the code would segfault due to the arrays being the wrong size.

This is not a candidate for stable branches because it only serves to
fix internal debugging code that you manually have to invoke by altering
the source code or using gdb.
