c778e8bf21 Add an Atomic.h to the System library, for providing a platform independent API
to low-level sync operations.

The only one present at the moment is MemoryFence(), and only for the platforms
for which I could easily discern the proper way to do it.  If your favorite platform
isn't represented, patches are welcome!

bed3aeff20 Update the names of the exception handling sjlj instrinsics to
llvm.eh.sjlj.* for better clarity as to their purpose and scope. Add
a description of llvm.eh.sjlj.setjmp to ExceptionHandling.html.
(llvm.eh.sjlj.longjmp documentation coming when that implementation is
added).

40d13bf382 Removing the HasBuiltinSetjmp flag and associated bits. Flagging the presence
of exception handling builtin sjlj targets in functions turns out not to 
be necessary. Marking the intrinsic implementation in the .td file as 
defining all registers is sufficient to get the context saved properly by 
the containing function.

e421c8f63d Change MachineInstrBuilder::addReg() to take a flag instead of a list of
booleans. This gives a better indication of what the "addReg()" is
doing. Remembering what all of those booleans mean isn't easy, especially if you
aren't spending all of your time in that code.

I took Jakob's suggestion and made it illegal to pass in "true" for the
flag. This should hopefully prevent any unintended misuse of this (by reverting
to the old way of using addReg()).

32cd719eba Add three new helper routines, getNoopOrZeroExtend,
getNoopOrSignExtend, and getTruncateOrNoop. These are similar
to getTruncateOrZeroExtend etc., except that they assert that
the conversion is either not widening or narrowing, as
appropriate. These will be used in some upcoming fixes.

18cc7c12b7 Add an int64_t variant of abs, for host environments
without one.  Use it where we were using abs on
int64_t objects.
(I strongly suspect the casts to unsigned in the
fragments in LoopStrengthReduce are not doing whatever
the original intent was, but the obvious change to
uint64_t doesn't work.  Maybe later.)

4bb5e9d1df Add support for GCC compatible builtin setjmp and longjmp intrinsics. This is
a supporting preliminary patch for GCC-compatible SjLJ exception handling. Note that these intrinsics are not designed to be invoked directly by the user, but
rather used by the front-end as target hooks for exception handling.

d13f674130 Factor the code for collecting IV users out of LSR into an IVUsers class,
and generalize it so that it can be used by IndVarSimplify. Implement the
base IndVarSimplify transformation code using IVUsers. This removes
TestOrigIVForWrap and associated code, as ScalarEvolution now has enough
builtin overflow detection and folding logic to handle all the same cases,
and more. Run "opt -iv-users -analyze -disable-output" on your favorite
loop for an example of what IVUsers does.

This lets IndVarSimplify eliminate IV casts and compute trip counts in
more cases. Also, this happens to finally fix the remaining testcases
in PR1301.

Now that IndVarSimplify is being more aggressive, it occasionally runs
into the problem where ScalarEvolutionExpander's code for avoiding
duplicate expansions makes it difficult to ensure that all expanded
instructions dominate all the instructions that will use them. As a
temporary measure, IndVarSimplify now uses a FixUsesBeforeDefs function
to fix up instructions inserted by SCEVExpander. Fortunately, this code
is contained, and can be easily removed once a more comprehensive
solution is available.

366006cfd3 Shrink wrapping in PEI:
- reduces _static_ callee saved register spills
  and restores similar to Chow's original algorithm.
- iterative implementation with simple heuristic
  limits to mitigate compile time impact.
- handles placing spills/restores for multi-entry,
  multi-exit regions in the Machine CFG without
  splitting edges.
- passes test-suite in LLCBETA mode.

Added contains() method to ADT/SparseBitVector.

f3461c73e8 Add memoization for getSCEVAtScope results for instructions
which are not analyzed with SCEV techniques, which can require
brute-forcing through a large number of instructions. This

particular, the loop in MD5Transform).
