This reverts commit r266002, r266011 and r266016.
They broke the msan bot.
Original message:
Add __atomic_* lowering to AtomicExpandPass.
AtomicExpandPass can now lower atomic load, atomic store, atomicrmw,and
cmpxchg instructions to __atomic_* library calls, when the target
doesn't support atomics of a given size.
This is the first step towards moving all atomic lowering from clang
into llvm. When all is done, the behavior of __sync_* builtins,
__atomic_* builtins, and C11 atomics will be unified.
Previously LLVM would pass everything through to the ISelLowering
code. There, unsupported atomic instructions would turn into __sync_*
library calls. Because of that behavior, Clang currently avoids emitting
llvm IR atomic instructions when this would happen, and emits __atomic_*
library functions itself, in the frontend.
This change makes LLVM able to emit __atomic_* libcalls, and thus will
eventually allow clang to depend on LLVM to do the right thing.
It is advantageous to do the new lowering to atomic libcalls in
AtomicExpandPass, before ISel time, because it's important that all
atomic operations for a given size either lower to __atomic_*
libcalls (which may use locks), or native instructions which won't. No
mixing and matching.
At the moment, this code is enabled only for SPARC, as a
demonstration. The next commit will expand support to all of the other
targets.

This is most evident when trying to print the "short" type, but
in theory could happen with chars too (although usually chars use
a different builtin type).
Additionally, we were using the wrong check when deciding whether
to print an enum definition as a global enum. We were checking
whether or not the enum was "nested", and if so saving it until
we print the class definition that it was nested in. But this is
not correct in rare situations where the enum is nested, but the
class that it's nested in does not have type information in the PDB.
So instead we check if there is a class definition for the parent
in the PDB. If so we save it for later, otherwise we print it.

[LoopUtils, LV] Fix PR27246 (first-order recurrences)
This patch ensures that when we detect first-order recurrences, we reject a phi
node if its previous value is also a phi node. During vectorization the initial
and previous values of the recurrence are shuffled together to create the value
for the current iteration. However, phi nodes are not widened like other
instructions. This fixes PR27246.
