665c644940 Fix two CPU profiler tests on ARM and MIPS simulators 
Use Simulator::get_pc instead of Simulator::get_register(pc) as the latter
will return value adjusted by Instruction::kPCReadOffset.

f4e563d391 Move StackTracer to sampler.h 
Apart from tests Sampler is the only client of StackTracer so it is logical to move it into sampler.h

99a0dabbaf Nuke SamplerRegistry 
The registry is a simple list of active Samplers but uses additional Mutex. Useful parts were merged into SamplerThread, others removed completely.

2e41f0ce1a pthreads seem to be fully supported on Linux and Android which allows to remove many #ifdefs. 
Also OS::Sleep(interval_) is used to pause sampling thread on all platforms. It makes no sense to send signal once 900mks to compensate 100mks delay on signal delivery as the signals would be delivered once 900mks.

9585ead1e9 This change is a continuation of the refactoring started in r14265. 
Renamed SignalSender to SamplerThread to match platforms that don't support signal sending.

Cygwin and Windows implementations are almost identical. Mac OS X uses different API to suspend thread but apart from that it is very similar to Windows implenenation.

1596afa7f9 Move *BSD and Solaris Sampler implementation into sampler.cc 
This is a first step to having profiler sampler implementation in one file with platform capabilities guarded with #ifdef. Otherwise we have very similar implementations scattered over platform-*.cc files which makes it hard to see differences and make changes.

The next steps will be to merge win32, Mac OS X and Cygwin implementations into sampler.cc They suspend profiled thread instead of sending a signal but apart from that the logic is pretty much the same. Then I'm going to move sampler-related code from log.* into sampler.*
