Dan Gohman 121302772d Don't let arbitrary calls disrupt nested retain+release pairs if
the retains and releases all use the same SSA pointer value.

Also, don't let CFG hazards disrupt nested retain+release pair
optimizations.

Dan Gohman 4767a1a117 Use an actual reverse-CFG reverse-postorder for the bottom-up traversal,
rather than plain postorder, so that CFG constructs like single-exit loops
are reliably visited in a sensible order.

Dan Gohman 6320f52ff4 Move the last uses of RetainFunc etc. over to using getRetainCallee() etc.
so that a declaration for objc_retain is created when needed if it doesn't
already exist. rdar://9825114.

Bill Wendling a78cd228c2 Revert r134893 and r134888 (and related patches in other trees). It was causing
an assert on Darwin llvm-gcc builds.

Assertion failed: (castIsValid(op, S, Ty) && "Invalid cast!"), function Create, file /Users/buildslave/zorg/buildbot/smooshlab/slave-0.8/build.llvm-gcc-i386-darwin9-RA/llvm.src/lib/VMCore/Instructions.cpp, li\
ne 2067.
