🐛 [Bug] EliminateExceptionOrPassPattern removes list append

[mfeliz-cruise]

Bug Description

Exception or pass elimination incorrectly identifies an if block with only a list append in it as a removable exception. This changes model behavior and creates incorrect outputs.

GRAPH: [Torch-TensorRT - Debug Build] - Found that node  = prim::If(%51)
block0():
  %10 : Tensor[] = aten::append(%mod_list.1, %y.1)
  -> ()
block1():
  -> ()
is an exception or pass node (EliminateChecks)

To Reproduce

Steps to reproduce the behavior:

class ExceptionEliminationError(nn.Module):
    def __init__(self):
        super(ExceptionEliminationError, self).__init__()
    def forward(self, x, y):
        mod_list = [x]
        if x.sum() > y.sum():
            mod_list.append(y)
        z = torch.cat(mod_list)
        return z

1. Attempt to compile the model above with torch-tensorrt

Expected behavior

The exception elimination pass should not remove this if.
