Nit pick on title: I've been following the seeming convention of `Windows: ` 
prefix instead of `WIN32: `. Joe, can you fix this when you commit?

Ship it!




After double-checking what these flags actually do, I'm going to
add some more information to the commit description:
```
The `/Zc:inline` flag tells the compiler to generate object files
but exclude symbols that are either unreferenced or have internal
linkage only.  This leads to smaller object files and faster linking.
See: https://msdn.microsoft.com/en-us/library/dn642448.aspx

The `/debug:FASTLINK` flag changes how the linker generates
program database files (PDB).  Instead of making a full copy of any
related debug information used by the library, this option instead
creates indexes to other PDBs, thereby cutting down on link-time
code generation.  This only affects DEBUG builds.
See: https://msdn.microsoft.com/en-us/library/xe4t6fc1.aspx
```

Review request for mesos, Andrew Schwartzmeyer, John Kordich, Joseph Wu, and Li 
Li.


Bugs: MESOS-7226
https://issues.apache.org/jira/browse/MESOS-7226


Repository: mesos


Description
---

When working on precompiled headers, we recognized that adding
some compile/link flags resulted in a 20% reduction in incremental
linkage time. This is NOT directly dependent on precompiled headers
(the improvement comes regardless of PCH).
