0ebcc18dec the latest assembler that runs on powerpc 10.4 machines doesn't 
support aligned comm.  Detect when compiling for 10.4 and don't
emit an alignment for comm.  THis will hopefully fix PR8198.

4fc55c0e02 Revert r114703 and r114702, removing the isConditionalMove flag from instructions. After further

f670bff621 Moved the PBQP allocator class out of the header and back in to the cpp file to hide the gory details. 
Allocator instances can now be created by calling createPBQPRegisterAllocator.

Tidied up use of CoalescerPair as per Jakob's suggestions.

Made the new PBQPBuilder based construction process the default. The internal construction process
remains in-place and available via -pbqp-builder=false for now. It will be removed shortly if the new
process doesn't cause any regressions.

d8735f1db1 Add support for ELF PLT references for ARM MC asm printing. Adding a 
new VariantKind to the MCSymbolExpr seems like overkill, but I'm not sure
there's a more straightforward way to get the printing difference captured.
(i.e., x86 uses @PLT, ARM uses (PLT)).

6543dacfac Rework passing parent pointers into complexpatterns, I forgot 
that complex patterns are matched after the entire pattern has
a structural match, therefore the NodeStack isn't in a useful
state when the actual call to the matcher happens.

matched, allow ComplexPatterns to opt into getting the parent node
of the operand being matched.

55043ef46a fix a long standing wart: all the ComplexPattern's were being 
passed the root of the match, even though only a few patterns
actually needed this (one in X86, several in ARM [which should
be refactored anyway], and some in CellSPU that I don't feel 
like detangling).   Instead of requiring all ComplexPatterns to
take the dead root, have targets opt into getting the root by
putting SDNPWantRoot on the ComplexPattern.

32ec32b690 finish pushing MachinePointerInfo through selectiondags. At this point, 
I think I've audited all uses, so it should be dependable for address spaces,
and the pointer+offset info should also be accurate when there.

03451a0e51 Add LiveInterval::find and use it for most LiveRange searching operations 
instead of calling lower_bound or upper_bound directly.

This cleans up the search logic a bit because {lower,upper}_bound compare
LR->start by default, and it is usually simpler to search LR->end.

Funnelling all searches through one function also makes it possible to replace
the search algorithm with something faster than binary search.

112cf9bc89 it's more elegant to put the "getConstantPool" and 
"getFixedStack" on the MachinePointerInfo class.  While
this isn't the problem I'm setting out to solve, it is the
right way to eliminate PseudoSourceValue, so lets go with it.
