[Mesa-dev] [PATCH 27/32] i965: Change resolve flags to enum

In the foreseeable future it doesn't seem to make sense to have multiple
resolve flags. What does make sense is to have the caller give an
indication to the lower layers what it things should be done for
resolve. The enum change distinguishes this binary selection.
v2: Make setting the hint more concise (Topi)
