Keith Randall 33b648c0e9 cmd/compile: fix ephemeral pointer problem on amd64
Make sure we don't use the rewrite ptr + (c + x) -> c + (ptr + x), as
that may create an ephemeral out-of-bounds pointer.

I have not seen an actual bug caused by this yet, but we've seen
them in the 386 port so I'm fixing this issue for amd64 as well.

The load-combining rules needed to be reworked somewhat to still
work without the above broken rule.

Update #37881
