[PATCH] D32530: [SVE] Scalable Vector IR Type

[Graham Hunter via Phabricator via llvm-commits]

- Adds a 'scalable' flag to VectorType
- Adds an 'ElementCount' class to VectorType to pass (possibly scalable) vector lengths, with overloaded operators.
- Modifies existing helper functions to use ElementCount
- Adds support for serializing/deserializing to/from both textual and bitcode IR formats
- Adds unit tests
- Updates documentation

I'm picking up this work from Paul now that the SVE documentation is available. See the previous version of this patch here: https://reviews.llvm.org/D27101

I'll post updated versions of the other patches in the series later.

Couldn't find a recommended reviewer for core IR changes in the code owners file, suggestions welcome.
