Replace llvm::DIBuilder::DisableDebugLocations() with two RAII interfaces
inspired by CodegenFunction::LexicalScope.
- NoLocation temporarily turns off debug locations altogether.
This is useful for emitting instructions that should be
counted towards the function prologue.
- BuiltinLocation temporarily switches to an artificial debug location
that has a valid scope, but no line information. This is useful when
emitting compiler-generated helper functions that have no source
location associated with them.
