[PATCH] D68309: GlobalISel: Implement widenScalar for G_INSERT_VECTOR_ELT

[Nicolai Hähnle via Phabricator via llvm-commits]

Yeah, it doesn't seem very relevant for the element argument, though precisely because of that I'd feel more comfortable with ANYEXT.

For the value argument it really does seem to make a codegen difference. It should be possible to avoid the SHL/ASHR sequence.
