It was testing the same buffer for differences:
memcmp(s1->user_stack.data, s1->user_stack.data, s1->user_stack.size)
I'm pretty sure this wasn't supposed to be dead code.

Adding mask info into struct regs_dump to make the registers information
compact.
The mask was always passed along, so logically the mask info fits more
into the struct regs_dump.

In fact the "sample parsing" test does not automatically check new
sample type bits - they must be added to the comparison logic.
Doing that shows that the test fails because the functions
perf_event__synthesize_sample() and perf_event__sample_event_size() have
not been updated with PERF_SAMPLE_TRANSACTION either.
