Pavel Labath d71fa331df [lldb] Fix inline function resolution for discontinuous functions (#116777)
The problem here is the assumption that the entire function will be
placed in a single section. This will ~never be the case for a
discontinuous function, as the point of splitting the function is to let
the linker group parts of the function according to their "hotness".

The fix is to change the offset computation to use file addresses
instead.

## Test that inline function resolution works when the function has been split
## into multiple discontinuous parts (and those parts are placed in different
## sections)
