-qemu-user-static crash when executing generated  NEON code due to failure to detect invalidation
-Description of problem:
-`qemu-arm-static` crashes 100% of times when attempting to run NEON code. The same executable, when run in `system` emulation mode, works without issue.
-
-I experience this particular issue when attempting to test GStreamer's Orc library with NEON codegen with QEMU user emulation.
-Steps to reproduce:
-1. Clone https://gitlab.freedesktop.org/gstreamer/orc.git
-2. Build with `meson setup build -Ddefault_library=static; meson compile -C build`
-3. Run `qemu-arm-static ./build/tools/orc-bugreport`
-Additional information:
-The crash always happens inside the same JIT code. It is not a memory access, so there is no reason for QEMU to report SIGSEGV:
-
-```
-Program received signal SIGSEGV, Segmentation fault.
