[dev.regabi] cmd/compile: add ir.TailCallStmt
This CL splits out ORETJMP as a new TailCallStmt node, separate from
the other BranchStmt nodes. In doing so, this allows us to change it
from identifying a function by *types.Sym to identifying one by
directly pointing to the *ir.Func.
While here, also rename the operation to OTAILCALL.
Passes toolstash -cmp.
