[CodeView] Add support for emitting column information
Column information is present in CodeView when the line table subsection
has bit 0 set to 1 in it's flags field. The column information is
represented as a pair of 16-bit quantities: a starting and ending
column. This information is present at the end of the chunk, after all
the line-PC pairs.
