Fix mlir windows buildbot after ec146cb7c0b4

ec146cb7c0b4 added two new ReducKinds for float maximum and minimum
(along with support in loop vectorizer).

Enumerate these kinds in SLPVectorizer to fix mlir windows build bot
errors:

C:\buildbot\mlir-x64-windows-ninja\llvm-project\llvm\lib\Transforms\Vectorize\SLPVectorizer.cpp(13883): error C2220: the following warning is treated as an error
