The AAExecutionDomain instance checks if a BB is executed by the main
thread only. Currently, this only checks the `__kmpc_kernel_init` call
for generic regions to indicate the path taken by the main thread. In
the new runtime, we want to be able to detect basic blocks even in SPMD
mode. For this we enable it to check thread-ID intrinsics being compared
to zero as well.
