* Allow templates to parse v8intrinsics
The `v8intrinsic` and `placeholders` parser plugins conflict, so enabling `placeholders` unconditionally was causing errors for V8's internal codemods. This allows them to set `syntacticPlaceholders = false` (so they'll use the legacy identifier format) and enable `v8intrinsic` by itself.
* Fix linter

This is the last step to make https://github.com/babel/babel/pull/9364 usable in Babel. I'm sorry for opening this PR so late, but I hope to get it in v7.4.
In this PR I added a new option to `@babel/template`, `syntacticPlaceholders: ?boolean`, which toggles between `%%foo%%` placeholders (when `true`) and `FOO` placeholders. If it isn't specified, Babel tries to be "smart" to avoid breaking backward compat: if `%%foo%%` is used `syntacticPlaceholders` defaults to `true`, otherwise to `false`.
0e58e252913efe84eba926cc9c9c19fb18d5c620 commit shows how some templates we used could be simplified by using this new placeholders syntax (we can't actually do it yet because we are importing `template` from `@babel/core` which could be an older version).
NOTE: Since I wanted to keep this PR as small as possible to make it easier to review, I didn't migrate `template.ast` to internally use the new syntax. It is an implementation detail, so it will be possible to change it in a patch release.
* Fix running flow on travis and update flow
- ensure bootstrap is run before running flow as we need some generated files for correctly doing typechecks
- ensure that we only ignore the build directory inside the babel folder as currently we ignore everything because travis checks out into ‘/home/travis/build/’
* Fix all flow errors
Supports:
```js
// these all should produce "code;" when generated
template`code;`();
template`${0}`(t.identifier('code'));
template`${'code'}`({ code: t.identifier('code') });
template`${t.identifier('code')}`()
template({})`code`();
```
Remove imports to lodash/assign and replace assign with Object.assign.
The lodash/assign is unnecessary for babel 7 as node >4 has the same
functionality built-in with Object.assign as used here.
This resolve the [issue 5353](https://github.com/babel/babel/issues/5353)
Removed `@flow` annotation from files that don't actually pass Flow check at the moment. These will be added back file by file once the files are properly converted to use Flow.
Closes#3064
I'm extremely stupid and didn't commit as I go. To anyone reading this
I'm extremely sorry. A lot of these changes are very broad and I plan on
releasing Babel 6.0.0 today live on stage at Ember Camp London so I'm
afraid I couldn't wait. If you're ever in London I'll buy you a beer
(or assorted beverage!) to make up for it, also I'll kiss your feet and
give you a back massage, maybe.
