Duncan P. N. Exon Smith f86505abdf IR: Extract macros from DILocation, NFC ... `DILocation` is a lightweight wrapper. Its accessors check for null and the correct type, and then forward to `MDLocation`. Extract a couple of macros to do the `dyn_cast_or_null<>` and default return logic. I'll be using these to minimize error-prone boilerplate when I move the new hierarchy into place -- since all the other subclasses of `DIDescriptor` will similarly become lightweight wrappers. (Note that I hope to obsolete these wrappers fairly quickly, with the goal of renaming the underlying types (e.g., I'll rename `MDLocation` to `DILocation` once the name is free).) llvm-svn: 229953		2015-02-20 02:28:49 +00:00
