* Format JSON literals like object literals
Following up on commit a42db30 (https://github.com/prettier/prettier/issues/2173),
this change makes it so that literals in JSON files are formatted as
they would be in an object literal. This normalizes trailing zeroes,
exponential notation, unnecessarily escaped characters, etc.
It works by using babylon to parse literals as expressions, and putting
the result in the AST instead of a `json-literal` node. Since JSON
string literals have to be double-quoted, there's a new
`__prettier__isJson` flag on each node, which is used by the printer to
force double-quotes.
* json: Check options.parser when formatting StringLiteral
This is instead of having a custom AST property. See
https://github.com/prettier/prettier/pull/2181#discussion_r122578251
* multiparser: Use babylon.parseExpression
See https://github.com/prettier/prettier/pull/2181#discussion_r122578354
* json: Don't split result AST node into two
See https://github.com/prettier/prettier/pull/2181#discussion_r122578499
* json: Don't use babylon parser to build expression nodes
See https://github.com/prettier/prettier/pull/2181#discussion_r122579052
* Revert "multiparser: Use babylon.parseExpression"
This reverts commit 3d7a4362880d39fac0cea88b5d0186a29538cf6f.
* Remove unused parameter from babylon parser
* json: Remove unused constructorTypes
Before, this error happened upon `yarn build`:
🚨 (commonjs plugin) Binding arguments in strict mode (49161:16) in /Users/josephfrazier/workspace/prettier/node_modules/typescript/lib/typescript.js
Among other things, this upgrades fsevents from 1.1.1 to 1.1.2, which
eliminates a `yarn` warning on OSX machines running Node.js 8. See here

* Add support for styled-jsx with expressions
* Lint
* Fix require for Node 4
* Re-create template-literal document when replacing placeholders
* Add support for styled-components with expressions
* Fix merge
* Move css library detection to functions
It turns out that by returning there, we didn't go through the line `delete ast.tokens` and the comments attachment logic would attach it to a random token. It's great that this fail-safe caught this bug!
Fixes#2111
In WebStorm file watcher, it doesn't make sense to reformat with Immediate file synchronization since the code jumps around while you type and if you sneak in a character while reformatting WebStorm pops a conflict alert.
So it's much saner to reformat on Save only.
