DescriptionReland of Make profiler no frame region detection code more robust [ia86/x64]
Upon collection of the stack trace if the current PC falls into
the frame building code, the top frame might be in a non-consistent
state. That leads to some of the frames could be missing from the
stack trace.
The patch makes it check instructions under current PC and if they
look like the frame setup/destroy code, it skips the entire sample.
Support for x86/x64
