commit 08d1d520616557f6ff7dd023e260ad6577e9e0e8

PR11173 Markers get a bad address in prelinked libraries.
Our literal_addr_to_sym_addr() function was just wrong. To compensate for
raw addresses read from elf (either given by the user or through a mark
transformation) we need to know what the elf_bias is (as returned by
dwfl_module_getelf) before feeding them to any libdwfl functions.
* tapsets.cxx (query_module_dwarf): Always add elf_bias to raw function or
statement addresses before calling query_addr().
(query_addr): Don't call literal_addr_to_sym_addr().
* dwflpp.h (literal_addr_to_sym_addr): Removed.
* dwflpp.cxx (literal_addr_to_sym_addr): Likewise.
