Opcodes SHADER_OPCODE_INTERLOCK and SHADER_OPCODE_MEMORY_FENCE are emitted as
brw_send_inst and at nir to brw conversion the desc field is set with scope and
flush type of the instruction.
But when brw_inst is converted to brw_send_inst all special fields of
brw_send_inst are set to 0, causing scope and flush type to always be 0.
So here calling lower_lsc_memory_fence_and_interlock() with brw_send_inst
parameter and storing the desc before brw_transform_inst_to_send().
I still have not figure out why we need do brw_transform_inst_to_send() even
if it is already a brw_send_inst but not doing so causes a segfault in
foreach_block_and_inst_safe(block, brw_inst, inst, s.cfg) of
brw_lower_logical_sends(), also other opcodes of that function does something
similar so I don't think that is wrong.
