[hwasan] Fix inline instrumentation.
This patch changes hwasan inline instrumentation:
Fixes address untagging for shadow address calculation (use 0xFF instead of 0x00 for the top byte).
Emits brk instruction instead of hlt for the kernel and user space.
Use 0x900 instead of 0x100 for brk immediate (0x100 - 0x800 are unavailable in the kernel).
Fixes and adds appropriate tests.
Patch by Andrey Konovalov.
