Make optimized debug builds link against debug CRT.

We recently had some XP issues on chromium.win after https://codereview.chromium.org/19384011/.

This might fix it - quote: "The most likely cause of the problem is a gyp (or similar) change that resulted in v8.dll linking against the release version of the crt (for a debug build). There are two MS VC related files: the crt and the c++ std lib (MSVCR100.DLL and MSVCP100D.DLL). The former is set to release, the latter to debug."

I am not entirely sure if this change fits to the linker options for debug level 2.
