Fix an exotic bug that only showed up in an internal test case.
SimpleRegisterCoalescing::JoinIntervals() uses CoalescerPair to determine if a copy is coalescable, and in very rare cases it can return true where LHS is not live - the coalescable copy can come from an alias of the physreg in LHS. llvm-svn: 106021
