Nikita Popov d3b86b79fa Reapply "[CodeGen][X86] Expand USUBSAT to UMAX+SUB, also for vectors"
Related to https://bugs.llvm.org/show_bug.cgi?id=40123.

Rather than scalarizing, expand a vector USUBSAT into UMAX+SUB,
which produces much better code for X86.

Reapplying with updated SLPVectorizer tests.
