i965/gen8/cs: Gen8 requires 64 byte alignment for push constant data
The BDW PRM Vol2a: Command Reference: Instructions, section MEDIA_CURBE_LOAD,
says that 'CURBE Total Data Length' and 'CURBE Data Start Address' are
64-byte aligned. This is different from previous gens, that were 32-byte
aligned.
v2 (Jordan):
- CURBE Data Start Address is also 64-byte aligned.
- The call to brw_state_batch should also use 64-byte alignment.
- Improve PRM reference.
v3:
* New patch from Jordan. Always align base and size to 64 bytes.
Fixes the following SSBO CTS tests on BDW:
ES31-CTS.shader_storage_buffer_object.basic-atomic-case1-cs
ES31-CTS.shader_storage_buffer_object.basic-operations-case1-cs
ES31-CTS.shader_storage_buffer_object.basic-operations-case2-cs
ES31-CTS.shader_storage_buffer_object.basic-stdLayout_UBO_SSBO-case2-cs
ES31-CTS.shader_storage_buffer_object.advanced-write-fragment-cs
ES31-CTS.shader_storage_buffer_object.advanced-indirectAddressing-case2-cs
ES31-CTS.shader_storage_buffer_object.advanced-matrix-cs
And many other CS CTS tests as reported by Marta Lofstedt.
(Commit message is from Iago, but in v3, code is from Jordan.)
