Ask if the eh_frame information for the given SymbolContext should be relied on even when it's the first frame in a stack unwind.
The CFI instructions from the eh_frame section are normally only valid at call sites – places where a program could throw an exception and need to unwind out. But some Modules may be known to the system as having reliable eh_frame information at all call sites. This would be the case if the Module's contents are largely hand-written assembly with hand-written eh_frame information. Normally when unwinding from a function at the beginning of a stack unwind lldb will examine the assembly instructions to understand how the stack frame is set up and where saved registers are stored. But with hand-written assembly this is not reliable enough – we need to consult those function's hand-written eh_frame information.

Ask if it is ok to try and load or unload an shared library (image).
The dynamic loader often knows when it would be ok to try and load or unload a shared library. This function call allows the dynamic loader plug-ins to check any current dyld state to make sure it is an ok time to load a shared library.
