CMake: set stack size to 2MB for MSVC builds
Compiling under Visual C++ 2012 with the default stack size of 1MB, the stack overflows at a depth of 216 template instantiations, well before the 256 default limit. This patch modifies the default MSVC stack size to 2MB. Patch by Yaron Keren! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192904 91177308-0d34-0410-b5e6-96231b3b80d8
