[mlir] BubbleUpBitCastForStridedSliceInsert::matchAndRewrite crashes with Assertion Failure "!empty()"

[Colloportus0]

MLIR built at commit a0dab4950
Reproduced with:

mlir-opt --test-vector-to-vector-lowering temp.mlir

temp.mlir:

func.func @func(%arg0: vector<f32>) -> vector<i32> {
  %0 = vector.bitcast %arg0 : vector<f32> to vector<i32>
  return %0 : vector<i32>
}

trace:

Assertion failed: (!empty()), function back, file ArrayRef.h, line 173.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
