[PATCH] Teach llvm-readobj to dump symbol records from a DEBUG_SYMBOL_SUBSECTION section.

[Zachary Turner]

Hi timurrrr, majnemer,

Subsections of type DEBUG_SYMBOL_SUBSECTION consist of a series of records.  Each record begins with a 4 byte length, followed by 4 byte type, followed by <length> bytes of data.  

This was already known, but we only dumped DEBUG_SYMBOL_TYPE_PROC_START and DEBUG_SYMBOL_TYPE_PROC_END.  This patch makes llvm-readobj dump the Length, type, and payload of other types of entries as individaul records so that they can be studied more closely.
