Added two new API functions to SBFrame:

const char *
SBFrame::GetFunctionName();

bool
SBFrame::IsInlined();


The first one will return the correct name for a frame. The name of a frame is:
- the name of the inlined function (if there is one)
- the name of the concrete function (if there is one)
- the name of the symbol (if there is one)
- NULL

We also can now easily check if a frame is an inline function or not.
