Extend perf-hwbreak.c selftest to test multiple DAWRs. Also add
testcase for testing 512 byte boundary removal.
Sample o/p:
# ./perf-hwbreak
...
TESTED: Process specific, Two events, diff addr
TESTED: Process specific, Two events, same addr
TESTED: Process specific, Two events, diff addr, one is RO, other is WO
TESTED: Process specific, Two events, same addr, one is RO, other is WO
TESTED: Systemwide, Two events, diff addr
TESTED: Systemwide, Two events, same addr
TESTED: Systemwide, Two events, diff addr, one is RO, other is WO
TESTED: Systemwide, Two events, same addr, one is RO, other is WO
TESTED: Process specific, 512 bytes, unaligned
