0684c8ebf9 Fix infinite recursion in the compiler.

fbef241709 Add a lint to detect unconditional recursion.
E.g. `fn foo() { foo() }`, or, more subtlely

    impl Foo for Box<Foo+'static> {
        fn bar(&self) {
            self.bar();
        }
    }

The compiler will warn and point out the points where recursion occurs,
if it determines that the function cannot return without calling itself.

Closes #17899.

65d14d2661 Rollup merge of #21498 - quantheory:master, r=alexcrichton
While trying to experiment with changes for some other issues, I noticed that the test for #15149 was failing because I have `/tmp` mounted as `noexec` on my Linux box, and that test tries to run out of a temporary directory. This may not be the most common case, but it's not rare by any means, because executing from a world-writable directory is a security problem. (For this reason, some kernel options/mods such as grsecurity also can prevent this on Linux.) I instead copy the executable to a directory created in the build tree, following the example of the `process-spawn-with-unicode-params` test.

After I made that change, I noticed that I'd made a mistake, but the test was still passing, because the "parent" process was not actually checking the status of the "child" process, meaning that the assertion in the child could never cause the overall test to fail. (I don't know if this has always been the case, or if it has something to do with either Windows or a change in the semantics of `spawn`.) So I fixed the test so that it would fail correctly, then fixed my original mistake so that it would pass again.

The one big problem with this is that I haven't set up any machines of my own so that I can build on Windows, which is the platform this test was targeted at in the first place! That might take a while to address on my end. So I need someone else to check this on Windows.

e5c1f166a8 Auto merge of #21458 - alexcrichton:remove-some-code, r=brson
The base64 support can be trivially removed (there are no in-tree users) and the regex support is a whopping 4k lines of code to maintain for a few non-critical uses in-tree. This commit migrates all current users in-tree away from regexes to custom matching code.

The most critical application affected by this migration is that the testing framework no longer considers filter arguments as regexes, but rather just a substring matching. It is expected that more featureful testing frameworks can evolve outside of the in-tree libtest version over time which can properly depend on libregex from crates.io.

6c29708bf9 regex: Remove in-tree version
The regex library was largely used for non-critical aspects of the compiler and
various external tooling. The library at this point is duplicated with its
out-of-tree counterpart and as such imposes a bit of a maintenance overhead as
well as compile time hit for the compiler itself.

The last major user of the regex library is the libtest library, using regexes
for filters when running tests. This removal means that the filtering has gone
back to substring matching rather than using regexes.

000dc07f71 Store a method-from-trait's impl in some cases when it is known.
This allows one to look at an `ExprMethodCall` `foo.bar()` where `bar`
is a method in some trait and (sometimes) extract the `impl` that `bar`
is defined in, e.g.

    trait Foo {
        fn bar(&self);
    }

    impl Foo for uint { // <A>
        fn bar(&self) {}
    }

    fn main() {
        1u.bar(); // impl_def_id == Some(<A>)
    }

This definitely doesn't handle all cases, but is correct when it is
known, meaning it should only be used for certain linting/heuristic
purposes; no safety analysis.

08246520c0 std: Relax Result::unwrap() to Debug
This commit relaxes the bound on `Result::unwrap` and `Result::unwrap_err` from
the `Display` trait to the `Debug` trait for generating an error message about
the unwrapping operation.

This commit is a breaking change and any breakage should be mitigated by
ensuring that `Debug` is implemented on the relevant type.

296777e50a Resolve type vars when inferring borrow kinds for upvars
As part of #20432, upvar checking is now moved out of regionck to its
own pass and before regionck. But regionck has some type resolution of
its own. Without them, now separated upvar checking may be tripped over
by residue `ty_infer`.

e9285f9e81 Auto merge of #21374 - dgrunwald:range-notation-fixes, r=nikomatsakis
This PR is intended as alternative to #20958. It fixes the same grammar inconsistencies, but does not increase the operator precedence of `..`, leaving it at the same level as the assignment operator.
For previous discussion, see #20811 and #20958.

Grammar changes:
* allow `for _ in 1..i {}` (fixes #20241)
* allow `for _ in 1.. {}` as infinite loop
* prevent use of range notation in contexts where only operators of high precedence are expected (fixes #20811)

Parser code cleanup:
* remove `RESTRICTION_NO_DOTS`
* make `AS_PREC` const and follow naming convention
* make `min_prec` inclusive
