Backport of #20219.
Avoid using any of intrinsics that related to broadcasting 64-bit integers
with MSVC 32-bit, even if they are apparently work on newer versions.
They had bad impact on the generated instructions, sometimes the
compiler deal with them without the respect of 32-bit mode which
lead to crush due to execute 64-bit instructions and other times
generate bad emulated instructions.
