commit 1f8592d1a615bef5bad1f255e761664e85d9e4f0

PR10305 Mark probes fail on prelinked shared library.
Mark probes rely on literal statement addresses, these are based on the
on-disk module address space. Introduce helper function to turn such
addresses into symbol addresses as expected by libdwfl. Also properly
adjust for dw bias when such addresses are used in dw queries.
* dwflpp.h (dwflpp::literal_addr_to_sym_addr): New method.
* dwflpp.cxx (query_cu_containing_address): Don't "globalize" address.
(literal_addr_to_sym_addr): New method.
* tapsets.cxx (query_module_dwarf): Turn literal addresses into symbol
addresses.
(query_dwarf_func): Likewise and adjust for dw module bias.
