The reversion apparently deleted the test/Transforms directory.
Will be re-reverting again.

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

Reapply the patches with a fix. Thanks Ilya and Hans for the reproducer!
This reverts commit r330416.
The issue was that removing predecessors invalidated uses that we stored
for rewrite. The fix is to finish manipulating with CFG before we select
uses for rewrite.

Revert r330413: "[SSAUpdaterBulk] Use SmallVector instead of DenseMap for storing rewrites."
Revert r330403 "Reapply "[PR16756] Use SSAUpdaterBulk in JumpThreading." one more time."
r330403 commit seems to crash clang during our integrate while doing PGO build with the following stacktrace:
#2 llvm::SSAUpdaterBulk::RewriteAllUses(llvm::DominatorTree*, llvm::SmallVectorImpl<llvm::PHINode*>*)
#3 llvm::JumpThreadingPass::ThreadEdge(llvm::BasicBlock*, llvm::SmallVectorImpl<llvm::BasicBlock*> const&, llvm::BasicBlock*)
#4 llvm::JumpThreadingPass::ProcessThreadableEdges(llvm::Value*, llvm::BasicBlock*, llvm::jumpthreading::ConstantPreference, llvm::Instruction*)
#5 llvm::JumpThreadingPass::ProcessBlock(llvm::BasicBlock*)
The crash happens while compiling 'lib/Analysis/CallGraph.cpp'.
r3340413 is reverted due to conflicting changes.

Hopefully, changing set to vector removes nondeterminism detected by
some bots, or the new assert will catch something.
This reverts commit r330180.

This reverts r330175. There are still stage3/stage4 miscompares.

One more, hopefully the last, bug is fixed: when forming UsesToRewrite
we should ignore phi operands coming from edges that we want to delete.
This reverts r329910.
