[mlir] Add function for checking if a block is inside a loop 2023-02-10T16:14:17+00:00 Tom Eccles tom.eccles@arm.com 2023-01-10T16:08:58+00:00 81a79ee446fe499e217144ae1cd505ede9021712 This function returns whether a block is nested inside of a loop. There can be three kinds of loop: 1) The block is nested inside of a LoopLikeOpInterface 2) The block is nested inside another block which is in a loop 3) There is a cycle in the control flow graph This will be useful for Flang's stack arrays pass, which moves array allocations from the heap to the stack. Special handling is needed when allocations occur inside of loops to ensure additional stack space is not allocated on each loop iteration. Differential Revision: https://reviews.llvm.org/D141401 
This function returns whether a block is nested inside of a loop. There
can be three kinds of loop:
  1) The block is nested inside of a LoopLikeOpInterface
  2) The block is nested inside another block which is in a loop
  3) There is a cycle in the control flow graph

This will be useful for Flang's stack arrays pass, which moves array
allocations from the heap to the stack. Special handling is needed when
allocations occur inside of loops to ensure additional stack space is
not allocated on each loop iteration.
