2017-09-14	rustc: Preallocate when building the dep graph	Alex Crichton	-0/+7
	This commit alters the `query` function in the dep graph module to preallocate memory using `with_capacity` instead of relying on automatic growth. Discovered in #44576 it was found that for the syntex_syntax clean incremental benchmark the peak memory usage was found when the dep graph was being saved, particularly the `DepGraphQuery` data structure itself. PRs like #44142 which add more queries end up just making this much larger! I didn't see an immediately obvious way to reduce the size of the `DepGraphQuery` object, but it turns out that `with_capacity` helps quite a bit! Locally 831 MB was used [before] this commit, and 770 MB is in use at the peak of the compiler [after] this commit. That's a nice 7.5% improvement! This won't quite make up for the losses in #44142 but I figured it's a good start.

	These explicit lifetimes can be ommitted because of lifetime elision rules. Instances were found using rust-clippy.
