Andy Polyakov fe9aa7642c appveyor.yml: engage VC-WIN64A-masm.
One of the reasons for why masm/ml64 is not [fully] supported is that
it's problematic to support multiple versions. But latest one usually
works and/or it's lesser problem to make it work. So idea here is to
have a "whistle" when it breaks, so that problems can be evaluated as
they emerge. It's kind of "best effort" thing, as opposite to "full
support".

# We can't make commitment to supporting Microsoft assembler,
# because it would mean supporting all masm versions. This in
# in turn is because masm is not really an interchangeable option,
# while users tend to have reasons to stick with specific Visual
# Studio versions. It's usually lesser hassle to make it work
# with latest assembler, but tweaking for older versions had
# proven to be daunting task. This is experimental target, for
# production builds stick with [up-to-date version of] nasm.
