Subject: cmd/compile: remove unnecessary code in keepAliveAt
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=a53589662719d0186e3ce3b965c082b829d0ce4c;p=gostls13.git

cmd/compile: remove unnecessary code in keepAliveAt

TypeWord and SrcRType are only needed for interface expression
conversion. Since CL 725180, the kept alive nodes are passed directly to
runtime.KeepAlive, so there's no interface conversion anymore.
