Teach LLDB to understand INLINE and INLINE_ORIGIN records in breakpad. They have the following formats: ``` INLINE inline_nest_level call_site_line call_site_file_num origin_num [address size]+ INLINE_ORIGIN origin_num name ``` `INLNIE_ORIGIN` is simply a string pool for INLINE so that we won't have duplicated names for inlined functions and can show up anywhere in the symbol file. `INLINE` follows immediately after `FUNC` represents the ranges of momery address that has functions inlined inside the function.
