Duncan P. N. Exon Smith e9d379c038 IR: Take advantage of -verify checks for MDExpression ... Now that we check `MDExpression` during `-verify` (r232299), make the `DIExpression` wrapper more strict: - remove redundant checks in `DebugInfoVerifier`, - overload `get()` to `cast_or_null<MDExpression>` (superseding `getRaw()`), - stop checking for null in any accessor, and - remove `DIExpression::Verify()` entirely in favour of `MDExpression::isValid()`. There is still some logic in this class, mostly to do with high-level iterators; I'll defer cleaning up those until the rest of the wrappers are similarly strict. llvm-svn: 232412		2015-03-16 21:03:55 +00:00
