[cfe-commits] PATCH: Minor refactoring: add CodeGenFunction::maybeInitializeDebugInfo()

[Alexey Samsonov]

Hi,

This small patch transforms occurrences of pattern
if (CGM.getModuleDebugInfo())
  DebugInfo = CGM.getModuleDebugInfo()
into a call
  maybeInitializeDebugInfo();

This is a simplification for a possible future fix of PR13942.
