Summary: I recently re-discovered that the unsinged stream operators of the lldb_private::Stream class have a surprising behavior in that they print the number in hex. This is all the more confusing because the "signed" versions of those operators behave normally. Now that, thanks to Raphael, each Stream class has a llvm::raw_ostream wrapper, I think we should delete most of our formatting capabilities and just delegate to that. This patch tests the water by just deleting the operators with the most surprising behavior. Most of the code using these operators was printing user_id_t values. It wasn't fully consistent about prefixing them with "0x", but I've tried to consistenly print it without that prefix, to make it more obviously different from pointer values.

# This tests a bug where we would incorrectly parse the size of an array if that
|
|
# size happened to match an existing DIE offset. This happened because we
|
|
# misinterpreted that value as a reference to a DIE specifying the VLA size even
|
|
# though the form was a data form (as it should be).
