Bug description:
  [Impact]

  renders GT3 haswells unusable

  [Test Case]

  use ubuntu with mesa < 9.1.4, notice how it hangs on login

  [Regression Potential]

  small, these are limited to GT3, and two commits to make them apply

  --

  The GPU hangs on login if the system has a GT3 version of Intel
  Haswell. This is fixed in 9.1.4 and by backporting these four commits
  to 9.0.x:

  210f2794f5c4fedc7 i965: Turn brw->urb.vs_size and gs_size into local 
variables.
  d4311138e47224ace i965: Use a variable for the push constant size in kB.
  acff9c2bbf6cf4d9a i965: Update URB partitioning code for Haswell's GT3 
variant.
  ed7fa63bbd375aaf6 i965: Add chipset limits for the Haswell GT3 variant.
