This commit fixes an accidental regression from #11526 detected on OSS-Fuzz. The
imm64constants created needed to be masked off to the type width to avoid having the upper bits set.<!--

cc @mmcloughlin @avanhatt -- this one is kind of interesting: the initial contribution had a Crocus proof but because I guess the prelude used there wasn't modeling the upper-bits-zeroed constraint on
iconsts, this slipped through. More fuel on the fire of modeling IR constraints precisely!
