Crash in PadDynamicAllocPass

[IanWood1]

What happened?

When investigating #19131, I ran the input IR on the gpu backend (vs cpu) and it ended up causing a crash in PadDynamicAllocPass.

Here (https://gist.github.com/IanWood1/c2a3ac9cc3801faedead58a958a20b88) is the stacktrace as well as the IR before the failing pass (https://gist.github.com/IanWood1/b8ca10625ffb5efdc1ce1780fab71847).

Steps to reproduce your issue

1. Grab https://gist.github.com/IanWood1/4b3885614cd81e5ba95b9e63586bf678
2. Run iree-compile --iree-hal-target-device=hip --iree-hip-target=gfx1100 --iree-dispatch-creation-enable-aggressive-fusion=true quantmm.mlir

Additional context

Looks like the upper bound is just below INT64_MAX, so it attempts to create a large memref subview
