Every now and then SystemZ programs built with ASan crash with
ERROR: AddressSanitizer: stack-overflow on address 0x040000000000
for no apparent reason. The problem is that
BufferedStackTrace::UnwindFast() is specialized for SystemZ: it takes
register 14 from the frame, however, IsValidFrame() is not
specialized, and does not guarantee that frame[14] is going to be a
valid memory access.
Fix by introducing per-arch kFrameSize and using it in IsValidFrame().
