Refactor `Vec::map_in_place` to move code out of `PartialVec`

Additionally, support zero-sized types.

mk: Start producing binary tarballs on windows

We may use these for creating combined rust/cargo installers

Makes it work on windows
Emit an error rather than ICEing for a missing built-in bound lang item.

closes #17392 

r? @nikomatsakis 

Kind of a first draft because I'm not sure if this is the right approach. I believe the general idea of giving an error rather than an ICE in obligation_for_builtin_bound is right, but not sure about returning an Option, etc.

Also, could probably have a better error message.
Include ChaCha pseudorandom generator
auto merge of #17563 : brson/rust/wintcbfix, r=thestinger

This is the bare minimum to stop using split stacks on Windows, fixing https://github.com/rust-lang/rust/issues/13259 and #14742, by turning on stack probes for all functions and disabling compiler and runtime support for split stacks on Windows.

It does not restore the out-of-stack error message, which requires more runtime work.

This includes a test that the Windows TCB is no longer being clobbered, but the out-of-stack test itself is pretty weak, only testing that the program exits abnormally, not that it isn't writing to bogus memory, so I haven't truly verified that this is providing the safety we claim.

A more complete solution is in https://github.com/rust-lang/rust/pull/16388, which has some unresolved issues yet.

Removed some unnecessary RefCells from resolve
auto merge of #17640 : brson/rust/wininst, r=alexcrichton

This makes the windows `make dist` target start producing binary tarballs, and tweaks install.sh so they work, in preparation for working on a combined Rust+Cargo installer.
librustc: Stop looking in metadata in type contents.

4x improvement in pre-trans compile time for rustc.
Fixes ICE when using reexported unit-like structs

Fixes that unit-like structs cannot be used if they are reexported and
used in another crate. The compiler fails with an ICE, because unit-like
structs are exported as DefFn and the expression `UnitStruct` is
interpreted as function pointer instead of a call to the constructor.

To resolve this ambiguity tuple-like struct constructors are now exported
as CtorFn. When `rustc::metadata::decoder` finds a CtorFn it sets a new
flag `is_ctor` in DefFn to true.

Relevant changes are in `rustc::metadata::{encoder, decoder}` and in
`rustc::middle::ty`.

Closes #12660 and #16973.
librustc: Forbid `..` in range patterns.

This breaks code that looks like:

    match foo {
        1..3 => { ... }
    }

Instead, write:

    match foo {
        1...3 => { ... }
    }

Closes #17295.
