Reapply r64300: Make sure the SCC pass manager initializes any contained function pass managers. Without this, simplify-libcalls would add nocapture attributes when run on its own, but not when run as part of -std-compile-opts or similar. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64443 91177308-0d34-0410-b5e6-96231b3b80d8 2009-02-13 07:15:53 +00:00			`; RUN: llvm-as < %s \| opt -inline -simplify-libcalls -functionattrs \| \`
