Change all of the build flags to switch /MD and /MDd into /MT, instead of just some of the targets. Fixes PR21241.

Disabling some MSVC warnings that are of questionable value. Note, these are disabled by default in LLVM as well, so there is precedence.

C4146: 'unary minus operator applied to unsigned type, result still unsigned'
C4291: ''declaration' : no matching operator delete found; memory will not be freed if initialization throws an exception'
C4800: ''type' : forcing value to bool 'true' or 'false' (performance warning)'

Do not set linker flags for MSVC; they are not the same thing as compiler flags. Note, this is already done in the add_compiler_rt_test test_suite function.

Cmake variables are global, which is why we would get crud like /machine:X86 in the list of compiler options for MSVC. Clear out the variable before attempting to enumerate arguments and set them.
