PR48169: Fix crash generating debug info for class non-type template parameters. It appears that LLVM isn't able to generate a DW_AT_const_value for a constant of class type, but if it could, we'd match GCC's debug info in this case, and in the interim we no longer crash.

Recommit r324107 again. The difference from the previous try is that we no longer directly access function declarations from position independent executables. It should work, but currently doesn't with some linkers. It now includes a fix to not mark available_externally definitions as dso_local. Original message: Start setting dso_local in clang. This starts adding dso_local to clang. The hope is to eventually have TargetMachine::shouldAssumeDsoLocal go away. My objective for now is to move enough of it to clang to remove the need for the TargetMachine one to handle PIE copy relocations and -fno-plt. With that it should then be easy to implement a -fno-copy-reloc in clang. This patch just adds the cases where we assume a symbol to be local based on the file being compiled for an executable or a shared library. llvm-svn: 324535

DebugInfo: Name class templates with default arguments consistently (both direct naming, and as a template argument for a function template) It's noteworthy that GCC has the same bug here, which is a bit surprising. Both Clang and GCC's bug is only for function template arguments that are themselves templates with default template arguments (f1<t1<int[, missing_default_here]>>). Probably because function name matching isn't generally necessary - whereas type matching is necessary for DWARF consumers to associate declarations and definitions across translation units, so the bug's been addressed there already - but continued to exist for function templates since it's fairly benign there. I came across this while working on a change that could reconstitute these pretty printed names based on the rest of the DWARF, reducing the size of the DWARF by not having to encode all the template parameters in the name string. That reconstitution code can't tell the difference between a defaulted argument or not, so couldn't create the current buggy-ish output. Making the names more consistent between direct and indirect references, and between function and class templates seems all to the good. (I fixed the function template version of this a few years back in 9fdd09a4ccd01feb8e00be22b17e944e46807746 - clearly I should've looked more closely and generalized the code better so it only had to be fixed once - well, doing that here now)
