Probe for acceptable precise_ip value. 
This is stupid, but it's exactly what perf does... Sigh.

707117c04f Build sanitization & Static analysis warning fixes 
- Wrapping FORCEINLINE & WIN32_LEAN_AND_MEAN definess with ifndef bc other libraries may define it and trigger redefinition warning
- Possibly contentious given tone in the manual (:P) but removing variable shadowing in TracySysTrace.cpp
  - Alternate Solution: Add #define TRACY_FORCE_SILENT_WARNINGS toggle-able flag. If flag is enabled, push/pop warning disables that have to be included in client code

6c0c508280 Ignore kernel-only stacks. 
It is common to receive duplicate stack traces for the same timestamp
(and thread), one containing proper user-space stack, and the second one
containing only kernel frames. Discard the second one, as there's no
documentation how this should be interpreted and the kernel stack is
mostly useless.
