From: Eric Pouech eric.pouech@gmail.com
When using an inline context which depth points towards the top level function (so when it's not strictly speaking an inline context), native falls back to picking information in the top level function.
So we do now in SymSetScopeFromInlineContext() and SymFromInlineContext() (instead of returning an error).

Store all the internal address ranges for an inline site (as we already do in dwarf debug info).
