Bug 1220525 - Add -Zc:inline for MSVC build. r=ted

-Zc:inliune introduces VS2013 update 2 to reduce build time.

https://blogs.msdn.microsoft.com/vcblog/2014/11/12/speeding-up-the-incremental-developer-build-scenario/

On my workstation (i7-3770, 4 cores 8 threads), the build time by clean build (--enable-optimize and --disable-debug) is the following.

With    -Zc:inline ... 39m44s
Without -Zc:inlune ... 43m52s

So we should use this option to improve build time.
