Fix windows-x86-debug compilation with python enabled using multi-target generator
[Patch by Leonid Mashinskiy] Visual Studio CMake generator is multi-target and does not define CMAKE_BUILD_TYPE, so Debug build on VS was failing due selection of release python library. This patch reverts back some of latest changes and fixes building by raw VS using CMake expression generators. Differential Revision: https://reviews.llvm.org/D66994 llvm-svn: 371090
