cca82149ad Add an unfolded offset field to LSR's Formula record. This is used to 
model constants which can be added to base registers via add-immediate
instructions which don't require an additional register to materialize
the immediate.

89fc9e8f5e Enable CFI on OS X. 
Currently the output should be almost identical to the one produced by CodeGen
to make the transition easier.

The only two differences I know of are:

* Some files get an extra advance loc of size 0. This will be fixed when
relaxations are enabled.
* The optimization of declaring an EH symbol as an external variable is not
implemented. This is a subset of adding the nounwind attribute, so we if really
this at -O0 we should probably do it at the IL level.

309db7c947 If converter was being too cute. It look for root BBs (which don't have 
successors) and use inverse depth first search to traverse the BBs. However
that doesn't work when the CFG has infinite loops. Simply do a linear
traversal of all BBs work just fine.

554daa67bd Be careful about scheduling nodes above previous calls. It increase usages of 
more callee-saved registers and introduce copies. Only allows it if scheduling
a node above calls would end up lessen register pressure.

Call operands also has added ABI restrictions for register allocation, so be
extra careful with hoisting them above calls.

1c3af779fc Thumb2 and ARM add/subtract with carry fixes. 
Fixes Thumb2 ADCS and SBCS lowering: <rdar://problem/9275821>.
t2ADCS/t2SBCS are now pseudo instructions, consistent with ARM, so the
assembly printer correctly prints the 's' suffix.

Fixes Thumb2 adde -> SBC matching to check for live/dead carry flags.

Fixes the internal ARM machine opcode mnemonic for ADCS/SBCS.
Fixes ARM SBC lowering to check for live carry (potential bug).
