    Description

      ClassFileParser::parse_linenumber_table use CompressedLineNumberWriteStream to turn line number information into a compact table for inclusion in each Method. Calls in that area are poorly inlined and shows up in startup profiles.

      Additionally, there are a few hacks in the area to disable compiler optimization on Windows due a bug in MSC 2005 that caused stack overflow when building. Testing show no sign that this code should exhibit any particular issues any longer.

      A cleanup in the area shows better inlining and slight improvements in startup.
