Names of structs, enums, traits, type aliases and type parameters (i.e. all identifiers that can be used as full paths in type position) are not allowed to match the names of primitive types.
See #20427 for more information.

This is a minor [breaking-change]

e4a9eb95ce Remove _VALUE from the float extremes constants. 
In `std::f32` and `std::f64`:

- `MIN_VALUE` → `MIN`
- `MAX_VALUE` → `MAX`
- `MIN_POS_VALUE` → `MIN_POSITIVE`

This matches the corresponding integer constants.

3d9528a8d8 Unstabilise words for now. 
It is not totally clear if we should just use whitespace, or if the full
unicode word-breaking algorithm is more correct. If there is demand we
can reconsider this decision (and consider the precise algorithm to use
in detail).

985fc7d09b std: Optimize Vec::from_iter 
This PR is an optimization of the `FromIterator` implementation of `Vec`

Benchmark: https://gist.github.com/alexcrichton/03d666159a28a80e7c70

Before:
    test macro_repeat1     ... bench:        57 ns/iter (+/- 1)
    test macro_repeat2     ... bench:        56 ns/iter (+/- 1)
    test map_clone1        ... bench:       828 ns/iter (+/- 13)
    test map_clone2        ... bench:       828 ns/iter (+/- 8)
    test repeat1           ... bench:      1104 ns/iter (+/- 10)
    test repeat2           ... bench:      1106 ns/iter (+/- 11)

After:
    test macro_repeat1     ... bench:        75 ns/iter (+/- 21)
    test macro_repeat2     ... bench:        59 ns/iter (+/- 31)
    test map_clone1        ... bench:        34 ns/iter (+/- 22)
    test map_clone2        ... bench:        52 ns/iter (+/- 21)
    test repeat1           ... bench:        34 ns/iter (+/- 11)
    test repeat2           ... bench:        33 ns/iter (+/- 12)

The idea behind this optimization is to avoid all bounds checks for space
already allocated into the vector. This may involve running the iterator twice,
but the first run of the iterator should be optimizable to a memcpy or memset if
possible.

The same treatment can in theory be applied to `Vec::extend` but the benchmarks
for that currently get *worse* if the change is applied. This appears to be some
LLVM optimizations going awry but it's seems prudent to land at least the
`collect` portion beforehand.

d1630970de Split the predicates listing out of TraitDef and TypeScheme and into a separate map, tcx.predicates, that is used for both traits and other kinds of items. Also use two newtypes to distinguish 
instantiated predicates from the raw, unsubstituted predicates extracted from the map.

32d0dbd49a librustc: Forbid partial reinitialization of uninitialized structures or 
enumerations that implement the `Drop` trait.

This breaks code like:

    struct Struct {
        f: String,
        g: String,
    }

    impl Drop for Struct { ... }

    fn main() {
        let x = Struct { ... };
        drop(x);
        x.f = ...;
    }

Change this code to not create partially-initialized structures. For
example:

    struct Struct {
        f: String,
        g: String,
    }

    impl Drop for Struct { ... }

    fn main() {
        let x = Struct { ... };
        drop(x);
        x = Struct {
            f: ...,
            g: ...,
        }
    }

Closes #18571.
