This commit fixes the code which adds lifetime markers in InlineFunction to skip zero-sized allocas instead of asserting on them. rdar://problem/20531155 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@235312 91177308-0d34-0410-b5e6-96231b3b80d8

; InlineFunction would assert inside the loop that leaves lifetime markers if
|
|
; there was an zero-sized AllocaInst. Check that it doesn't assert and doesn't
|
|
; leave lifetime markers in that case.
