b1eede1281 Fix the LoopUnroller to handle nontrivial loops and partial unrolling. 
These are not individual bug fixes. I had to rewrite a good chunk of
the unroller to make it sane. I think it was getting lucky on trivial
completely unrolled loops with no early exits. I included some fairly
simple unit tests for partial unrolling. I didn't do much stress
testing, so it may not be perfect, but should be usable now.

4147f39769 Temporarily revert r135528 which distinguishes between two copies of one 
inlined variable, based on the discussion in PR10542.

This explodes the runtime of several passes down the pipeline due to
a large number of "copies" remaining live across a large function. This
only shows up with both debug and opt, but when it does it creates
a many-minute compile when self-hosting LLVM+Clang. There are several
other cases that show these types of regressions.

All of this is tracked in PR10542, and progress is being made on fixing
the issue. Once its addressed, the re-instated, but until then this
restores the performance for self-hosting and other opt+debug builds.

Devang, let me know if this causes any trouble, or impedes fixing it in
any way, and thanks for working on this!

762797d1af An algorithm for incrementally updating LoopInfo within a 
LoopPassManager. The incremental update should be extremely cheap in
most cases and can be used in places where it's not feasible to
regenerate the entire loop forest.

- "Unloop" is a node in the loop tree whose last backedge has been removed.
- Perform reverse dataflow on the block inside Unloop to propagate the
  nearest loop from the block's successors.
- For reducible CFG, each block in unloop is visited exactly
  once. This is because unloop no longer has a backedge and blocks
  within subloops don't change parents.
- Immediate subloops are summarized by the nearest loop reachable from
  their exits or exits within nested subloops.
- At completion the unloop blocks each have a new parent loop, and
  each immediate subloop has a new parent.

26689ac37e New approach to r136737: insert the necessary fences for atomic ops in platform-independent code, since a bunch of platforms (ARM, Mips, PPC, Alpha are the relevant targets here) need to do essentially the same thing.

73e7dced38 Add an isSSA() flag to MachineRegisterInfo. 
This flag is true from isel to register allocation when the machine
function is required to be in SSA form.  The TwoAddressInstructionPass
and PHIElimination passes clear the flag.

The SSA flag wil be used by the machine code verifier to check for SSA
form, and eventually an assertion can enforce it in +Asserts builds.
This will catch the common target error of creating machine code with
multiple defs of a virtual register.

55ba816883 Misc optimizer+codegen work for 'cmpxchg' and 'atomicrmw'. They appear to be 
working on x86 (at least for trivial testcases); other architectures will
need more work so that they actually emit the appropriate instructions for
orderings stricter than 'monotonic'. (As far as I can tell, the ARM, PPC,
Mips, and Alpha backends need such changes.)

ff03048c13 LangRef and basic memory-representation/reading/writing for 'cmpxchg' and 
'atomicrmw' instructions, which allow representing all the current atomic
rmw intrinsics.

The allowed operands for these instructions are heavily restricted at the
moment; we can probably loosen it a bit, but supporting general
first-class types (where it makes sense) might get a bit complicated,
given how SelectionDAG works.

As an initial cut, these operations do not support specifying an alignment,
but it would be possible to add if we think it's useful. Specifying an
alignment lower than the natural alignment would be essentially
impossible to support on anything other than x86, but specifying a greater
alignment would be possible.  I can't think of any useful optimizations which
would use that information, but maybe someone else has ideas.

Optimizer/codegen support coming soon.

If true and 'model' parameter is not an absolute path, a temp directory will be prepended.
Make it true by default to match current behaviour.

6d51d26a24 Add an extension point to the CommandLine library where clients can 
register extra version information to be printed. This is designed to
allow those tools which link in various targets to also print those
registered targets under --version.

Currently this printing logic is embedded into the Support library
directly; a huge layering violation. This is the first step to hoisting
it out into the tools without adding lots of duplicated code.

40c7e4142e There are two ways to map a variable to its lexical scope. Lexical scope information is embedded in MDNode describing the variable. It is also available as a part of DebugLoc attached with DBG_VALUE instruction. DebugLoc attached with an instruction is less reliable in optimized code so use information embedded in the MDNode.

34ad6db8b9 - Move CodeModel from a TargetMachine global option to MCCodeGenInfo.

  code model for JIT. This eliminates the ugly hack in TargetMachine where
  code model is changed after construction.

1360bc8eb0 During bottom up fast-isel, instructions emitted to materalize registers are at top of basic block and do not have debug location. This may misguide debugger while entering the basic block and sometimes debugger provides semi useful view of current location to developer by picking up previous known location as current location. Assign a sensible location to the first instruction in a basic block, if it does not have one location derived from source file, so that debugger can provide meaningful user experience to developers in edge cases.

c48e1ef0e2 Introduce the 'makeArrayRef(...)' family of functions, which fills a similar role for ArrayRef<> as std::make_pair() fills for std::pair<>: they return the right instantiation of ArrayRef<T> based on the types of the parameters. 
They mostly mirror the ArrayRef constructors, with two exceptions:
 * There's no function mirroring the default constructor because it wouldn't have any parameters to deduce the right ArrayRef<T> from.
 * There's an explicit SmallVector<T> overload in addition to the SmallVectorImpl<T> overload. Without it, the single-element overload would try to create an ArrayRef<Smallvector<T> > because it's a better match according to the overloading rules. (And both overloads are used in the current tree, so neither is redundant)
