Inline a function when the always_inline attribute
is set even when it contains a indirect branch. The attribute overrules correctness concerns like the escape of a local block address. This is for rdar://16501761 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206429 91177308-0d34-0410-b5e6-96231b3b80d8
