TypeScript Version: 2.1.4

Code

{
  "compilerOptions": {
    "target": "es5",
    "jsx": "react",
    "declaration": false,
    "importHelpers": true,
    "noEmitHelpers": true,
    "lib": [ "dom", "es6" ],
    "moduleResolution": "node",
    "module": "commonjs",
    "experimentalDecorators": true,
    "inlineSourceMap": true,

    "noImplicitAny": false,
    "noImplicitReturns": true,
    "noFallthroughCasesInSwitch": true,
    "baseUrl": "."
  }
}
tsc --traceResolution > trace.out

Expected behavior:
Compiler should not try to resolve tslib

Actual behavior:
Compile attempts to resolve tslib for each file compiled, trace.out contains the following text hundreds of times:
