(Large project) FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

[JoshuaKGoldberg]

Spin-off of #16165.

On large project with (very rough ball park) 100k .ts lines and another ~50k .d.ts lines, tsc --watch will consistently run out of memory after >= dozen recompiles.

TypeScript Version: 2.3

tsconfig.json:

{
    "compilerOptions": {
        "experimentalDecorators": true,
        "noImplicitAny": true,
        "noResolve": false,
        "target": "ES5"
    }
}

Eventual error:

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

I get this same issue on a smaller project using watchify with tsify with typescript@next

EDIT: Adding skipLibCheck: true to my tsconfig.json fixes this.

@JoshuaKGoldberg can you give TS 2.5-rc a try and let us know if you are still seeing failures? and if so please share enlistment instructions with @sandersn to investigate further.

https://www.nuget.org/packages/Microsoft.TypeScript.MSBuild/2.5.0 (yes, it should be rc tagged but it isn't at the moment)
