rL352847: [llvm-symbolizer][test] Rename and tweak tests using llvm-symbolizer
Summary

There are a few tests called llvm-symbolizer* in the DebugInfo test area. These really are testing either the DebugInfo or Symbolizer library, rather than the llvm-symbolizer tool itself, so this patch renames them to be clearer that they aren't explicitly tests for llvm-symbolizer (such tests belong in test/tools/llvm-symbolizer).

This patch also reinstates the copying of a DWO file, removed previously in rL352752. The test needs this so that it could possibly fail.

Finally, some of the tests have been simplified slightly by removing unnecessary switches and/or unused check-prefixes.

Built from the following source:
void f1();
__attribute__((always_inline)) inline void f2() { f1(); }
void f3() { f2(); }
Compiled to assembly with clang, modified the skeleton CU to remove the
high/low pc (& update the CU length field and abbrev to match) & then
compile/objcopy to make the .o and .dwo.
Ensure that the f2 inlined frame is not included - it's inefficient to have to
go and load all the debug info and search for the address ranges, so assume
that a lack of ranges on the CU means the CU covers no addresses.
