Description
The SVE support patch https://github.com/DynamoRIO/dynamorio/pull/5835 resulted in the following unit tests only failing on QEMU, always passing on native AArch64 hardware:
```
code_api|client.drx_buf-test
code_api|sample.memval_simple
code_api|client.drreg-test
```
This issue is to investigate whether these are due to the SVE patch or a QEMU defect, see https://github.com/DynamoRIO/dynamorio/pull/5835#issuecomment-1663745348
