Rebuilding (after touching certain files) is crazy slow because includes are out of control. Many of these files we need to rebuild are cctests which pull in more includes than they need.

This patch is based on alph's CL https://codereview.chromium.org/2128613004/. This patch makes GetStackSample propogate the register state when using simulator helper, and adds argument to avoid using register state from simulator when pass the native register state.

This patch does five things: 1. Extracts sampler as libsampler to provide sampling functionality support. 2. Makes SampleStack virtual so embedders can override the behaviour of sample collecting. 3. Removes sampler.[h|cc]. 4. Moves sampling thread into log.cc as workaround to keep the --prof functionality. 5. Creates SamplerManager to manage the relationship between samplers and threads. The reason we port hashmap.h is that in debug mode, STL containers are using mutexes from a mutex pool, which may lead to deadlock when using asynchronously signal handler. Currently libsampler is used in V8 temporarily.
