* tapsets.cxx (dwflpp::literal_stmt_for_local): Handle dwarf
pointer-to-1-byte-means-char case (found in PR 1187)
* parse.cxx (parse_symbol): Eliminate use of "." from target
symbol parser, conflicting with string concatenation operator.
* staptree.h (target_symbol::component_type) Eliminate
comp_struct_pointer_member, since . and -> are considered the
same now.
* staptree.cxx (target_symbol::print): Likewise.
* testsuite/buildok/seventeen.stp: Test solution on PR 1191.
* testsuite/buildok/six.stp: Test working portion of PR 1155.
* testsuite/semko/nineteen.stp: Unresolved portion of PR 1155.
