Assuming that the value on top of stack is return address for a frameless invocation is error-prone. Corresponding logic was removed from profile-generator.cc in r14205 (see https://code.google.com/p/v8/source/diff?spec=svn14205&r=14205&format=side&path=/branches/bleeding_edge/src/profile-generator.cc ) and now it is time to remove it from the tick processor.
Since the tos is not used anymore by profiler it is also removed from TickSample.

Fix CPU profiling for Crankshaft.
...
The main issue was due to multiple recompilations of functions. Now
code objects are grouped by function using SFI object address.
JSFunction objects are no longer tracked, instead we track SFI object
moves. To pick a correct code version, we now sample return addresses
instead of JSFunction addresses.
tools/{linux|mac|windows}-tickprocessor scripts differentiate
between code optimization states for the same function
(using * and ~ prefixes introduced earlier).
DevTools CPU profiler treats all variants of function code as
a single function.
ll_prof treats each optimized variant as a separate entry, because
it can disassemble each one of them.
tickprocessor.py not updated -- it is deprecated and will be removed.

CPU profiler: add secure profiles by filtering out functions using security tokens.
...
As several pages can run in a single V8 instance, it is possible to
have functions from different security contexts intermixed in a single
CPU profile. To avoid exposing function names from one page to
another, filtering is introduced.
The basic idea is that instead of capturing return addresses from
stack, we're now capturing JSFunction addresses (as we anyway work
only with JS stack frames.) Each JSFunction can reach out for
context's security token. When providing a profile to a page, the
profile is filtered using the security token of caller page. Any
functions with different security tokens are filtered out (yes, we
only do fast path check for now) and their ticks are attributed to
their parents.

rate, current time is periodically queried and processed along with
actual sampling ticks count.
