Subject: ir_reader: Return a specific ir_dereference variant.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0fd665ca63ba37b9a3022f21a8d9f363530e2038;p=mesa.git

ir_reader: Return a specific ir_dereference variant.

There's really no reason to return the base class when we have more
specific information about what type it is.
