99dca4fde7 Remove the "WantsWholeFile" concept, as it's no longer needed. CBE
and the others use the regular addPassesToEmitFile hook now, and
llc no longer needs a bunch of redundant code to handle the
whole-file case.

bbf33b38aa Mostly rewrite RegAllocFast.
Sorry for the big change. The path leading up to this patch had some TableGen
changes that I didn't want to commit before I knew they were useful. They
weren't, and this version does not need them.

The fast register allocator now does no liveness calculations. Instead it relies
on kill flags provided by isel. (Currently those kill flags are also ignored due
to isel bugs). The allocation algorithm is supposed to work with any subset of
valid kill flags. More kill flags simply means fewer spills inserted.

Registers are allocated from a working set that contains no aliases. That means
most allocations can be done directly without expensive alias checks. When the
working set runs out of registers we do the full alias check to find new free
registers.

Move EmitTargetCodeForMemcpy, EmitTargetCodeForMemset, and
EmitTargetCodeForMemmove out of TargetLowering and into
SelectionDAGInfo to exercise this.

651804c3d6 MC/Mach-O x86_64: Switch to using fragment atom symbol.
- This eliminates getAtomForAddress() (which was a linear search) and
   simplifies getAtom().
 - This also fixes some correctness problems where local labels at the same
   address as non-local labels could be assigned to the wrong atom.

81043ee5dc The getDefaultSubtargetFeatures method of SubtargetFeature did actually return a
string of features for that target. However LTO was using that string to pass
into the "create target machine" stuff. That stuff needed the feature string to
be in a particular form. In particular, it needed the CPU specified first and
then the attributes. If there isn't a CPU specified, it required it to be blank
-- e.g., ",+altivec". Yuck.

Modify the getDefaultSubtargetFeatures method to be a non-static member
function. For all attributes for a specific subtarget, it will add them in like
normal. It will also take a CPU string so that it can satisfy this horrible
syntax.

e89f1c4ee7 Fix PR6875:
This includes a patch by Roman Divacky to fix the initial crash.

Move the actual addition of passes from *PassManager::add to
*PassManager::addImpl.  That way, when adding printer passes we won't
recurse infinitely.

Finally, check to make sure that we are actually adding a FunctionPass
to a FunctionPassManager before doing a print before or after it.
Immutable passes are strange in this way because they aren't
FunctionPasses yet they can be and are added to the FunctionPassManager.
