perf(dep_graph): Avoid allocating a set on when the number reads are … …small `reserve_and_rehash` takes up 1.4% of the runtime on the `packed-simd` benchmark which I believe is due to the number of reads are very low in many cases (see https://github.com/rust-lang/rust/pull/50565 for instance). This avoids allocating the set until we start allocating the `reads` `SmallVec` but it is possible that a lower limit might be better (not tested since the improvement will be hard to spot either way).

Rename rustc guide This is in preparation for https://github.com/rust-lang/rustc-guide/issues/470 Needs to be merged after we actually rename the guide. Have used this to rename: `git grep -l 'rustc_guide' | xargs sed -i 's/rustc_guide/rustc_dev_guide/g'` `git grep -l 'rustc-guide' | xargs sed -i 's/rustc-guide/rustc-dev-guide/g'` `git grep -l 'rustc guide' | xargs sed -i 's/rustc guide/rustc dev guide/g'`

2020-01-27Collisions in the dep-graph due to path-reuse are rare but can occur.Felix S. Klock II-9/+30
So, instead of ICE'ing, just fail to mark green in such cases (for `DepKind::{Hir, HirBody, CrateMetadata}`). Fix #62649.

2019-12-17Revert "Auto merge of #67362 - Mark-Simulacrum:par-4-default, r=alexcrichton"Mark Rousskov-7/+7
This reverts commit 3ed3b8bb7b100afecf7d5f52eafbb70fec27f537, reversing changes made to 99b89533d4cdf7682ea4054ad0ee36c351d05df1. We will reland a similar patch at a future date but for now we should get a nightly released in a few hours with the parallel patch, so this should be reverted to make sure that the next nightly is not parallel-enabled.

self-profiling: Add events for metadata loading (plus a small dep-tracking optimization) This PR - adds self-profiling events related to loading things from crate metadata - makes the compiler cache the `DepNodeIndex` of upstream crates, so that they don't have to be looked up over and over. The commits are best reviewed in isolation. Self-profiling tracking issue: https://github.com/rust-lang/rust/issues/58967 r? @Mark-Simulacrum cc @wesleywiser
