[LLVMdev] clang doesn't set code column in debug info records

[Yuri]

This is maybe a minor issue, but it is obvious when one looks at debug 
info produced by clang. Such records are normally created by the code 
like this:
Instruction->setDebugLoc(llvm::DebugLoc::get(Line, Column, Scope));
and it appears that Column is always zero.
