e92e4a4342 Token chain results are not always the first or last result. Consider copyfromreg nodes, where they are the middle result (the flag result is last)

19343b85fd Add support for targets (like Alpha) that have terminator instructions which
use virtual registers.  We now allow the first instruction in a block of
terminators to use virtual registers, and update phi elimination to correctly
update livevar when eliminating phi's.  This fixes a problem on a testcase
