* tapsets.cxx (dwflpp::express_as_string): New function.
Extracted from dwflpp::literal_stmt_for_local() so that
dwflpp::literal_stmt_for_return() could also call it.
(dwflpp::literal_stmt_for_local): Portion extracted to create
dwflpp::express_as_string().
(dwflpp::literal_stmt_for_return): New function. Adds support for
new symbolic access ("$return") to return value in .return
probes. Fixes PR 1132.
(target_variable_flavour_calculating_visitor::visit_target_symbol):
Calls dwflpp::literal_stmt_for_return() when in a return probe and
the variable name is "$return".
(dwarf_var_expanding_copy_visitor::visit_target_symbol): Ditto.
* stapfuncs.5.in: Noted that the retval() function is deprecated.
* stapprobes.5.in: Corrected the name of the return value
variable.
* tapset/return.stp: Marked the retval() function as deprecated.
* testsuite/semko/return01.stp: Added new test.
* testsuite/semko/return02.stp: Ditto.
