Msvc crashes with "INTERNAL COMPILER ERROR" when iterating over an `std::initializer_list` in a constexpr constructor. Explicitly use the iterator instead.

This patch is part of the series to make flang compilable with MS Visual Studio <http://lists.llvm.org/pipermail/flang-dev/2020-July/000448.html>.
