Handle REG_SEQUENCE with implicitly defined operands. Code like that would only be produced by bugpoint, but we should still handle it correctly. When a register is defined by a REG_SEQUENCE of undefs, the register itself is undef. Previously, we would create a register with uses but no defs. Fixes part of PR10520. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136401 91177308-0d34-0410-b5e6-96231b3b80d8
