The control flow finalizer would sometimes use an ALU_POP_AFTER instruction before the vetex fetch clause instead of using a POP instruction after it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199917 91177308-0d34-0410-b5e6-96231b3b80d8

; This tests for a bug where vertex fetch clauses right before an ENDIF
|
|
; instruction where being emitted after the ENDIF. We were using ALU_POP_AFTER
|
|
; for the ALU clause before the vetex fetch instead of emitting a POP instruction
|
|
; after the fetch clause.
