Nicholas Nethercote ac26b883bf Improve spans on evaluated cfg_attrs. 
When converting something like `#![cfg_attr(cond, attr)]` into
`#![attr]`, we currently duplicate the `#` token and the `!` token. But
weirdly, there is also this comment:

// We don't really have a good span to use for the synthesized `[]`
// in `#[attr]`, so just use the span of the `#` token.

Maybe that comment used to be true? But now it is false: we can
duplicate the existing delimiters (and their spans and spacing), much
like we do for the `#` and `!`.

This commit does that, thus removing the incorrect comment, and
improving the spans on `Group`s in a few proc-macro tests.

UI Tests

This folder contains rustc's UI tests.

Test Directives (Headers)

Typically, a UI test will have some test directives / headers which are special comments that tell compiletest how to build and intepret a test.

As part of an on-going effort to rewrite compiletest (see https://github.com/rust-lang/compiler-team/issues/536), a major change proposal to change legacy compiletest-style headers // <directive> to ui_test-style headers //@ <directive> was accepted (see https://github.com/rust-lang/compiler-team/issues/512.

An example directive is ignore-test. In legacy compiletest style, the header would be written as

// ignore-test

but in ui_test style, the header would be written as

//@ ignore-test

compiletest is changed to accept only //@ directives for UI tests (currently), and will reject and report an error if it encounters any comments // <content> that may be parsed as an legacy compiletest-style test header. To fix this, you should migrate to the ui_test-style header //@ <content>.
