Change internal/cpu feature configuration to use GODEBUG=cpu.feature1=value,cpu.feature2=value... instead of GODEBUGCPU=feature1=value,feature2=value... . This is not a backwards compatibility breaking change since GODEBUGCPU was introduced in go1.11 as an undocumented compiler experiment. Fixes #28757 Change-Id: Ib21b3fed2334baeeb061a722ab1eb513d1137e87 Reviewed-on: https://go-review.googlesource.com/c/149578 Run-TryBot: Martin Möhrmann <martisch@uos.de> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org>
