[PATCH] D71786: RFC: [Support] On Windows, add optional support for rpmalloc

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

I haven't found time to review this yet, but this is still a very interesting change, and I hope to get to it soon.

Some other things I wanted to do in this space are:

- Histogram most commonly allocated AST node types
- Try raising BumpPtrAllocator "slab" size above 4096, that seems too small. Most AST nodes are allocated with BumpPtrAllocator.

These changes would likely only affect parsing speed, not middle/backend speed which dominates thinlto time.
