[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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@241764 91177308-0d34-0410-b5e6-96231b3b80d8
