Forcing an unaligned LDREX access in aarch32, QEMU fails the following assert:
target-arm/helper.c:5921:regime_el: code should not be reached
Running this snippet both baremetal and on top of Linux will trigger
the problem:

Qemu does not generally perform alignment checks. However, the ARM ARM
requires implementation of alignment exceptions for a number of cases
including LDREX, and Windows-on-ARM relies on this.
This change adds plumbing to enable alignment checks on loads using
MO_ALIGN, a do_unaligned_access hook
