Summary:                    ninja generator relinks all executables after
incremental build in LLVM due to extra .lib output file
Description: 
Old versions of cmake would generate this ninja target:
build bin\opt.exe: CXX_EXECUTABLE_LINKER ...

Recent versions (3.2+) generate this target:
build bin\opt.exe lib\opt.lib: CXX_EXECUTABLE_LINKER_RSP_FILE

Since this is an executable, no .lib file should be generated, right? Why does
the linker build rule even list the /implib flag? Maybe this is some
functionality I'm unaware of, but so far as I can tell it is extraneous.
