@randall77 @dr2chase This cherrypick's CL still needs review.

Update: I'm considering it, it's not set in stone yet. :)

@heschi @mknyszek Actually, both the CLs are reviewed. I think they just need someone in @golang/release team to submit.

[release-branch.go1.17] cmd/compile: only update source type when pro…
759a921 
…cessing struct/array

This is backport of CL 3651594, with the test from CL 360057.

CL 360057 fixed missing update source type in storeArgOrLoad. However,
we should only update the type when processing struct/array. If we
update the type right before calling storeArgOrLoad, we may generate a
value with invalid type, e.g, OpStructSelect with non-struct type.

Fixes #49392
