2ecf52b841 [dev.regabi] cmd/compile: separate CommStmt from CaseStmt 
Like go/ast and cmd/compile/internal/syntax before it, package ir now
has separate concrete representations for switch-case clauses and
select-communication clauses.

Passes toolstash -cmp.

a59d26603f [dev.regabi] cmd/compile: use []*CaseStmt in {Select,Switch}Stmt 
Select and switch statements only ever contain case statements, so
change their Cases fields from Nodes to []*CaseStmt. This allows
removing a bunch of type assertions throughout the compiler.

CaseStmt should be renamed to CaseClause, and SelectStmt should
probably have its own CommClause type instead (like in go/ast and
cmd/compile/internal/syntax), but this is a good start.

Passes toolstash -cmp.

40818038bf [dev.regabi] cmd/compile: change CaseStmt.Vars to Var 
There's only ever one variable implicitly declared by a CaseStmt. It's
only a slice because we previous used Rlist for this.

Passes toolstash -cmp.

Similar to previous CL: take advantage of better constructor APIs for
translating ASTs from syntax to ir.
