Remove code that analyzes tos values from tickprocessor
...
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.

Include more information in --prof log.
...
Main changes:
- include timestamps in profile ticks
- include code kind in code create events
- time execution in external code
- changed plot-timer-events.js to show the code kind being executed

Fix issue 553: function frame is skipped in profile when compare stub is called.
...
The problem appeared due to a fact that stubs doesn't create a stack
frame, reusing the stack frame of the caller function. When building
stack traces, the current function is retrieved from PC, and its
callees are retrieved by traversing the stack backwards. Thus, for
stubs, the stub itself was discovered via PC, and then stub's caller's
caller was retrieved from stack.
To fix this problem, a pointer to JSFunction object is now captured
from the topmost stack frame, and is saved into stack trace log
record. Then a simple heuristics is applied whether a referred
function should be added to decoded stack, or not, to avoid reporting
the same function twice (from PC and from the pointer.)

Add automatic tests for Tick Processor, take two.
...
Now tests can be run from any directory. Location of test data is now determined using test file location provided by 'testcfg.py' script.
Tested under Linux, Mac, and Windows.
