--- Comment #1 from Roland Scheidegger <sroland at vmware.com> ---
It looks like llvm 7.0+ got rid of the umul intrinsic (the optimized umul code
was once used by draw but nowadays it's only used for these 32x32->64bit muls).
Need to update the code to follow the autoupgrade pattern of llvm instead.
(For unsigned mul that would be bitcast/and/mul/shuffle, for signed it's
bitcast/shl/ashr/mul/shuffle.)
