mesa: added gl_program::IndirectRegisterFiles field

Now drivers, etc. can know which register files are accessed with
indirect addressing.  Before we just checked gl_program::NumAddressRegs
but didn't know if that was the constant buffer, temp regs, or what.

The only user of this new field so far will be the gallium state tracker.
