These reports provide information tied to token positions in the
Dart source program.
SourceReport can generate multiple kinds of reports. Right now it
implements code coverage and call site reports. In the future it
could provide, for example, valid breakpoint sites or source-level
profiles.
Scripts are refered to by index within the report and a script table
is tacked on the end. This avoids a bit of duplication.
In a future cl I will expose this reporting through the vm service.
After that, we can remove our older coverage/callsite code.

Very simple, sample coverage report:
{
"type": "SourceReport",
"ranges": [
{
"scriptIndex": 0,
"startPos": 0,
"endPos": 4,
"compiled": true,
"coverage": {
"hits": [],
"misses": []
}
},
{
"scriptIndex": 0,
"startPos": 6,
"endPos": 10,
"compiled": false
},
{
"scriptIndex": 0,
"startPos": 12,
"endPos": 39,
"compiled": true,
"coverage": {
"hits": [ 23 ],
"misses": [ 32 ]
}
}
],
"scripts": [
{
"type": "@Script",
"fixedId": true,
"id": "libraries\/15\/scripts\/test-lib",
"uri": "test-lib",
"_kind": "script"
}
]
}
