2020-01-05Auto merge of #67808 - Marwes:projection_normalization_recurse, r=nikomatsakisbors-0/+3
perf: Don't recurse into types that do not need normalizing A bit speculative at this stage but profiling shows that type folding takes up a substantial amount of time during normalization which may indicate that many types may be folded despite there being nothing to normalize

2020-01-03Rollup merge of #67595 - ohadravid:impl-trait-does-not-live-long-enough, ↵Yuki Okushi-1/+1
r=estebank Suggest adding a lifetime constraint for opaque type Fixes #67577, where code like this: ``` struct List { data: Vec<String>, } impl List { fn started_with<'a>(&'a self, prefix: &'a str) -> impl Iterator<Item=&'a str> { self.data.iter().filter(|s| s.starts_with(prefix)).map(|s| s.as_ref()) } } ``` will show this error: ``` Compiling playground v0.0.1 (/playground) error[E0597]: `prefix` does not live long enough --> src/lib.rs:6:47 | 5 | fn started_with<'a>(&'a self, prefix: &'a str) -> impl Iterator<Item=&'a str> { | -- lifetime `'a` defined here --------------------------- opaque type requires that `prefix` is borrowed for `'a` ... ``` but without suggesting the lovely `help: you can add a constraint..`. r? @estebank

This PR moves `src/librustc/hir/lowering{/, .rs}` to its own crate (`librustc_ast_lowering`) which is very self-contained (only `fn lower_crate` and `trait Resolver` are exposed). r? @Mark-Simulacrum
