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.
