d4d276faaf Rollup merge of #38842 - abonander:proc_macro_attribute, r=jseyfried
Implement `#[proc_macro_attribute]`

This implements `#[proc_macro_attribute]` as described in https://github.com/rust-lang/rfcs/pull/1566

The following major (hopefully non-breaking) changes are included:

* Refactor `proc_macro::TokenStream` to use `syntax::tokenstream::TokenStream`.
    * `proc_macro::tokenstream::TokenStream` no longer emits newlines between items, this can be trivially restored if desired
    * `proc_macro::TokenStream::from_str` does not try to parse an item anymore, moved to `impl MultiItemModifier for CustomDerive` with more informative error message

* Implement `#[proc_macro_attribute]`, which expects functions of the kind `fn(TokenStream, TokenStream) -> TokenStream`
    * Reactivated `#![feature(proc_macro)]` and gated `#[proc_macro_attribute]` under it
    * `#![feature(proc_macro)]` and `#![feature(custom_attribute)]` are mutually exclusive
    * adding `#![feature(proc_macro)]` makes the expansion pass assume that any attributes that are not built-in, or introduced by existing syntax extensions, are proc-macro attributes

* Fix `feature_gate::find_lang_feature_issue()` to not use `unwrap()`

    * This change wasn't necessary for this PR, but it helped debugging a problem where I was using the wrong feature string.

* Move "completed feature gate checking" pass to after "name resolution" pass

    * This was necessary for proper feature-gating of `#[proc_macro_attribute]` invocations when the `proc_macro` feature flag isn't set.

Related to #30172, and loosley based on #38551.

At the moment, this PR is in a pretty rough state, but I wanted to get some feedback to see if I'm going in the right direction.

I hope the Mentor label of #30172 is still applicable, even though it's a year old 😄

0a7420acd1 travis: Move glibc backwards in time
This commit updates the compilers for many of the artifacts that we're producing
on Travis. These compilers are all compiled by crosstool-ng as they're currently
done for the images in which we're building all our cross compiled compilers.

The purpose of this commit is that when we ship binaries the artifacts won't
require a newer glibc, but rather be as compatible as possible with Linux
distributions by working with a very old version of glibc.

This commit always allocates a new matrix entry for the i686/x86_64 builder.
This builder is dedicated to just producing artifacts and eventually we'll
expand it to building other tools like Cargo and the RLS. The other builders
testing i686 and x86_64 won't use these historical toolchains.

e8f9d2d43a travis: Get an emscripten builder online
This commit adds a new entry to the Travis matrix which will execute emscripten
test suites. Along the way it updates a few bits of the test suite to continue
passing on emscripten, such as:

* Ignoring i128/u128 tests as they're presumably just not working (didn't
  investigate as to why)
* Disabling a few process tests (not working on emscripten)
* Ignore some num tests in libstd (#39119)
* Fix some warnings when compiling

f0b4207598 Auto merge of #39136 - keeperofdakeys:proc-macro-doc-test, r=alexcrichton
Stop warning when doc testing proc macro crates

Fixes #39064

Add the test option to the session struct that is passed
to phase_2_configure_and_expand function inside the
rustdoc test module.

This prevents the warning code from triggering when
parsing proc_macro_derive attributes, just like when
`--test` is normally invoked.

This change makes the warning disappear, but I'm not sure what else it might change. So this early PR is mainly to run the test suite, and to get feedback.

8e29b4d387 Auto merge of #38465 - japaric:msp430-interrupt, r=eddyb
calling convention for MSP430 interrupts

This calling convention is used to define interrup handlers on MSP430 microcontrollers. Usage looks like this:

``` rust
#[no_mangle]
#[link_section = "__interrupt_vector_10"]
pub static TIM0_VECTOR: unsafe extern "msp430-interrupt" fn() = tim0;

unsafe extern "msp430-interrupt" fn tim0() {
  P1OUT.write(0x00);
}
```

which generates the following assembly:

``` asm
Disassembly of section __interrupt_vector_10:

0000fff2 <TIM0_VECTOR>:
    fff2:       10 c0           interrupt service routine at 0xc010
