Print reasonable representations of type names in llvm-nm, readelf and readobj
For type values that do not have proper names, print reasonable representation in llvm-nm, llvm-readobj and llvm-readelf, matching GNU tools.s Fixes PR41713. Differential Revision: https://reviews.llvm.org/D65537 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@368451 91177308-0d34-0410-b5e6-96231b3b80d8
