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.

Extract hardcoded error strings into a single place and replace them with enum.
...
I'd like to propagate bailout reason to cpu profiler.
So I need to save it into heap object SharedFunctionInfo.
But:
1) all bailout reason strings spread across all the sources.
2) they are native strings and if I convert them into String then I may have a performance issue.
3) one byte is enough for 184 bailout reasons. Otherwise we need 8 bytes for the pointer.
Also I think it would be nice to have error strings collected in one place.
In that case we will get additional benefits:
It allows us to keep this set of messages under control.
It gives us a chance to internationalize them.
It slightly reduces the binary footprint.
From the other hand the developers have to add new strings into that enum.

Revert windows-specific part of r15937 for debug level 1.
...
The change in r15937 might have broken a mozilla test under windows. See https://codereview.chromium.org/19384011/
Each case of debug 0,1,2 is now stated explicitly for better clarity in the msvs section. This causes some minor code duplications, which we can squeeze again after toolchain.gypi is in a stable state.
