cmd/compile: internal compiler error: Value live at entry. It shouldn't be. [1.16 backport]

[gopherbot]

@mdempsky requested issue #44355 to be considered for backport to the next 1.16 minor release.

@gopherbot please backport to Go 1.16

[mdempsky]

This is a compiler crash on valid code that used to work with Go 1.15.

[cagedmantis]

Approved. This is a serious issue.

Closed by merging ddeae6b to release-branch.go1.16.
