This reverts the commit 7d8a119213
because GCC is now configured to not emit ldp/stp Qn instructions for
consecutive 32-byte loads and stores, and the nested interrupt handling
failure due to the missing emulation of these instructions no longer
occurs.
For more details, refer to the GitHub issue #49491 and #49806.
