[Bug tapsets/10625] New: nested functions aren't probeable

["jistone at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

In loc2c.c, there are several definitions of nested inline functions, but they
are not visible to stap.  For example, translate() has a nested function called
deepen(), yet:

$ stap -l 'process("stap").function("deepen")'
semantic error: no match while resolving probe point
process("stap").function("deepen")

We get our functions from elfutils' dwarf_getfuncs(), but that function only
looks at the direct children of the CU.  For nested functions, the subprogram
DIE occurs as a child of the function that contains it.

Finding nested functions will probably require scanning through the DIEs within
each discovered function, but that will probably slow us down quite a bit.
