How do you know there was no read before this write? Did you check it?
memory_region_is_mapped() only indicates if the memory region is mapped

memory_region_is_mapped() is the wrong check, we actually want to check

For example, memory regions mapped via an alias, such as NVDIMMs,
currently don't make memory_region_is_mapped() return "true". As the

Playing with memory_region_is_mapped(), I realized that memory regions

We use INDEX_op_insn_start to make the start of instruction
boundaries. If we don't do it in the .insn_start hook things get
confused especially now plugins want to use that marking to identify
the start of instructions and will bomb out if it sees instrumented
ops before the first instruction

With -m32, size_t is generally only a uint32_t. That makes clang
complain that in the assertion
assert(qiov->size <= INT64_MAX);
the range of the type of qiov->size (size_t) is too small for any of its
values to ever exceed INT64_MAX.
Cast qiov->size to uint64_t to silence clang.

Enabling this for AArch64 gives us testing of the feature in CI.
