Matthew Dempsky c310c688ff cmd/compile, runtime: simplify multiway select implementation ... This commit reworks multiway select statements to use normal control flow primitives instead of the previous setjmp/longjmp-like behavior. This simplifies liveness analysis and should prevent issues around "returns twice" function calls within SSA passes. test/live.go is updated because liveness analysis's CFG is more representative of actual control flow. The case bodies are the only real successors of the selectgo call, but previously the selectsend, selectrecv, etc. calls were included in the successors list too. Updates #19331.
