`delay_span_bug` when codegen cannot select obligation
Fix#69602, introduced in #60126 by letting the compiler continue past
type checking after encountering errors.
even more clippy cleanups
* Don't pass &mut where immutable reference (&) is sufficient (clippy::unnecessary_mut_passed)
* Use more efficient &&str to String conversion (clippy::inefficient_to_string)
* Don't always eval arguments inside .expect(), use unwrap_or_else and closure. (clippy::expect_fun_call)
* Use righthand '&' instead of lefthand "ref". (clippy::toplevel_ref_arg)
* Use simple 'for i in x' loops instead of 'while let Some(i) = x.next()' loops on iterators. (clippy::while_let_on_iterator)
* Const items have by default a static lifetime, there's no need to annotate it. (clippy::redundant_static_lifetimes)
* Remove redundant patterns when matching ( x @ _ to x) (clippy::redundant_pattern)
more clippy cleanups
* Don't use .ok() before unwrapping via .expect() on a Result.
* Use .map() to modify data inside Options instead of using .and_then(|x| Some(y))
* Use .as_deref() instead of .as_ref().map(Deref::deref)
* Don't use "if let" bindings to only check a value and not actually bind anything.
* Use single-char patter on {ends,starts}_with and remove clone on copy type.
const limit for CTFE
I tried to tackle the first steps for this issue.
The active feature flag does link to the issue below, I think this has to change, because there should be a tracking issue?
1679a7647d/src/librustc_feature/active.rs (L530)
Also, I only put up the storage of the limit like "recursion_limit" but created a seperate file in the same place. Since I guess the invocation happens seperately.
https://github.com/TheSamsa/rust/blob/const-limit/src/librustc/middle/const_limit.rs
If this does not hold up for the issue and since there is a time pressure, just reject it.
hopefully this does not put more load on you than I expected...
submodules: update clippy from 8b7f7e66 to 74eae9dc
Changes:
````
Rustup to rust-lang/rust#69506
Revive rls integration test
use question mark operator
Add regression test
Use `try_eval_usize` over `eval_usize`
Add path for display trait
Use lang items instead of get_trait_def_id where possible
Update stderr
Don't lint debug formatting in debug impl
Whitelist unused attribute for use items.
add test for #5238
````
Makes clippy tests pass again.
r? @oli-obk
Correctly reject `TraitCandidate` in all cases
Follow up to #69255, addresses #69629.
When `self.select_trait_candidate(trait_ref)` returned `Err(_)`, `result` wasn't being set to `NoMatch`, causing invalid methods to be selected.
Changes:
````
Apply suggestions from code review
Simplify if_chain.
Move NumericLiteral to its own module.
Included binary and octal cases.
Resolve false positives for hex int cast.
Test for unnecessary_cast of hex int literal.
run-rustfix
Lint `if let Some` in question_mark lint
Add restrictive pat use in full binded struct
Update test case answers to match cargo dev fmt
Ran cargo dev fmt

nightly: bootstrap from 1.42.0-beta.5 (4e1c5f0e9 2020-02-28)
This beta snapshot has the llvm miscompilation fix included and is bootstrapped from a stable version that also has it included.
Stabilize assoc_int_consts associated int/float constants
The next step in RFC https://github.com/rust-lang/rfcs/pull/2700 (tracking issue #68490). Stabilizing the associated constants that were added in #68325.
* Stabilize all constants under the `assoc_int_consts` feature flag.
* Update documentation on old constants to say they are soft-deprecated and the new ones should be preferred.
* Update documentation examples to use new constants.
* Remove `uint_macro` and use `int_macro` for all integer types since the macros were identical anyway.

Invoke OptimizerLastEPCallbacks in PreLinkThinLTO
The default ThinLTO pre-link pipeline does not include optimizer last
extension points. Thus, when using the new LLVM pass manager & ThinLTO
& sanitizers on any opt-level different from zero, the sanitizer
function passes would be omitted from the pipeline.
Add optimizer last extensions points manually to the pipeline, but guard
registration with stage check in the case this behaviour changes in the
future.
