The Panic instruction initiates a panic with value X.

A Panic instruction must be the last instruction of its containing BasicBlock, which must have no successors.

NB: 'go panic(x)' and 'defer panic(x)' do not use this instruction; they are treated as calls to a built-in function.

Pos() returns the ast.CallExpr.Lparen if this panic was explicit in the source.

Example printed form:

panic t0
