Drop <def,dead> flags when merging into an unused lane. The new coalescer can merge a dead def into an unused lane of an otherwise live vector register. Clear the <dead> flag when that happens since the flag refers to the full virtual register which is still live after the partial dead def. This fixes PR14079. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165877 91177308-0d34-0410-b5e6-96231b3b80d8
