Manman Ren c2f32d7e24 [Inliner] revert r17101 since it causes a performance regression on MD5.
See rdar://16676020 for details.
r17101 tries to solve r16761933 by checking non-direct recursions in
the call graph. We are in discussion of solving it in a different way.

Todo: figure out why r17101 causes a preformance regression.
