Preserves a sequence point during the final scheduling phase.

This scheduler variant has an optional integer constant expression operand, indicating a positive or negative cycle offset between the two separated basic blocks. For example, with a negative offset (-N) you can allow a partial overlap (up to N cycles) between two consecutive blocks.

#define __aie_scheduler_separator_local

Preserves a sequence point during the final scheduling phase, but only on a local loop.
