[MSVC2015/Cycles] MSVC2015 before update 3 produce invalid builds

I'm not quite sure where the codegen bug gets triggered but it's easily
noticeable in the barcelona scene. (extra saturated leafs and illumination
on the right ledge of the pool)

2013 buildbot reference image:
{F320792}

2015 With no updates (compiler version 19.00.23026)
{F320793}

2015 With Update 2 (Compiler version 19.00.23918)
{F320794}

2015 With Update 3 (Compiler version 19.00.24210)
{F320795}

This patch blocks all compiler builds before update 3 in a similar way we
did for msvc 2013 update 4
