<pre>We should revisit how we emit debug info.
Currently (r224856) DWARF is emitted whenever we emit any DI. On Windows, we
also emit COFF/CodeView line table DI.
This is not optimal as:
a) There's no way to disable DWARF but keep CVLT
b) There's no way to disable CVLT on Windows and get only DWARF
c) DWARF significantly increases the binary size
d) AddressSanitizer doesn't need DWARF at all and at the same time it's very
sensitive to extra binary size for large apps</pre>
