This seems to be https://bugs.llvm.org/show_bug.cgi?id=35865, I'm investigating whether https://reviews.llvm.org/rL322106 helps.

Log:
  Pull in r322106 from upstream llvm trunk (by Alexey Bataev):

    [COST]Fix PR35865: Fix cost model evaluation for shuffle on X86.

    Summary:
    If the vector type is transformed to non-vector single type, the
    compile may crash trying to get vector information about non-vector
    type.

    Reviewers: RKSimon, spatel, mkuper, hfinkel

    Subscribers: llvm-commits

    Differential Revision: https://reviews.llvm.org/D41862

  This should fix "Not a vector MVT!" errors when building the
  games/dhewm3 port.
