This PR adds an intrinsic to create barriers that can be used with existing barrier intrinsics for synchronization. The prior method of barrier allocation was to use `alloc_buffer` e.g. as follows `barrier = T.alloc_buffer([1], "uint64", scope="shared")` and then pass the pointer and offset to that barrier allocation for use in the barrier intrinsics. This was a functional interface, but also caused problems with alignment of other non-barrier shared memory allocations. See removed workarounds marked with `TODO` in the tests in this PR. At the expense of the additional `create_barriers` intrinsic we get a simplified interface using barrier ID rather than pointer / offset passed to the barrier intrinsics and more low-level codegen control which is used in this PR to solve the alignment issue. -- This is an automated message from the Apache Git Service.
