llvm-symbolizer: Avoid infinite recursion walking dwos where the dwo contains a dwo_name attribute The dwo_name was added to dwo files to improve diagnostics in dwp, but it confuses tools that attempt to load any dwo named by a dwo_name, even ones inside dwos. Avoid this by keeping track of whether a unit is already a dwo unit, and if so, not loading further dwos. llvm-svn: 267241

REQUIRES: shell
Use %T instead of cd'ing to Output directly. %T expands to Output if not configured differently. llvm-svn: 267281
