Clang chooses to use a __vectorcall optimization in which
address pointers are vector loaded in the gpu::invoke_primitive.
This results in a segfault when stack alignment is absent.
Since the GPU transformer does not rely on CPU for compute,
we disable the optimizations of the emitted function.

Double curly-brace initialization (required by clang for non-templated functions) causes a compiler error in centos. (#1561)

Since the warning is not enforced in clang for templated functions, we can get around the centos compiler error with only a single set of curly braces here.
