arm64: Add uprobe support
This patch adds support for uprobe on ARM64 architecture.
Unit tests for following have been done so far and they have been found
working
1. Step-able instructions, like sub, ldr, add etc.
2. Simulation-able like ret, cbnz, cbz etc.
3. uretprobe
4. Reject-able instructions like sev, wfe etc.
5. trapped and abort xol path
6. probe at unaligned user address.
7. longjump test cases
Currently it does not support aarch32 instruction probing.
