D55348 replaced @objc_msgSend with @llvm.objc.msgSend in tests
together with many other objc intrinsics. However, this is not a
recognized objc intrinsic (https://llvm.org/docs/LangRef.html#objective-c-arc-runtime-intrinsics)
and does not receive special treatment by LLVM. It's likely that
uses of this function were renamed by accident.
This came up in D106013, because the address of @llvm.objs.msgSend
is taken, something which is normally not allowed for intrinsics.

As it's causing some bot failures (and per request from kbarton).
This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

We're moving ARC optimisation and ARC emission in clang away from runtime methods
and towards intrinsics. This is the part which actually uses the intrinsics in the ARC
optimizer when both analyzing the existing calls and emitting new ones.

The `BasicBlock::getFirstInsertionPt` call may return `std::end` for the
BB. Dereferencing the end iterator results in an assertion failure
"(!NodePtr->isKnownSentinel()), function operator*". Ensure that the
returned iterator is valid before dereferencing it. If the end is
returned, move one position backward to get a valid insertion point.
