[PATCH] D51032: [ARM] Avoid injecting constant islands in movw+movt pairs on Windows

[Eli Friedman via Phabricator via llvm-commits]

Can we change the way we model these movw+movt pairs so it isn't so fragile?  If these pairs are illegal to split on Windows, I'd prefer to model it as a pseudo-instruction until the asmprinter.  Otherwise you're going to be fighting obscure issues in every pass that runs after ARMExpandPseudo.
