Anna Zaks 83f1495fcb [analyzer] Inline ObjC class methods. 
- Some cleanup(the TODOs) will be done after ObjC method inlining is
complete.
- Simplified CallEvent::getDefinition not to require ISDynamicDispatch
parameter.
- Also addressed Jordan's comments from r160530.

Ted Kremenek bb81ffb342 Update ExprEngine's handling of ternary operators to find the ternary expression 
value by scanning the path, rather than assuming we have visited the '?:' operator
as a terminator (which sets a value indicating which expression to grab the
final ternary expression value from).

Nick Lewycky 7d0f110cb3 It's not safe to blindly remove invoke instructions. This happens when we 
encounter an invoke of an allocation function. This should fix the dragonegg
bootstrap. Testcase to follow, later.

Jim Ingham 279ceecf65 Add a call to "sync" a thread state before checkpointing registers in preparation for 
calling functions.  This is necessary on Mac OS X, since bad things can happen if you set
the registers of a thread that's sitting in a kernel trap.

Manman Ren e8c6b15137 Update testing case for Atom when disabling rematerialization in 
TwoAddressInstructionPass.

to commit r160749.

Ted Kremenek b1fcddfc6a Remove experimental invalid iterators checker from the codebase until we have the time 
to fix all the issues.  Currently the code is essentially unmaintained and buggy, and
needs major revision (with coupled enhancements to the analyzer core).

Manman Ren cc1dc6dc11 Disable rematerialization in TwoAddressInstructionPass. 
It is redundant; RegisterCoalescer will do the remat if it can't eliminate
the copy. Collected instruction counts before and after this. A few extra
instructions are generated due to spilling but it is normal to see these kinds
of changes with almost any small codegen change, according to Jakob.

This also fixed rdar://11830760 where xor is expected instead of movi0.

Jakob Stoklund Olesen cef9a618b1 Preserve 2-addr constraints in ConnectedVNInfoEqClasses. 
When a live range splits into multiple connected components, we would
arbitrarily assign <undef> uses to component 0. This is wrong when the
use is tied to a def that gets assigned to a different component:

  %vreg69<def> = ADD8ri %vreg68<undef>, 1

The use and def must get the same virtual register.

Fix this by assigning <undef> uses to the same component as the value
defined by the instruction, if any:

  %vreg69<def> = ADD8ri %vreg69<undef>, 1

This fixes PR13402. The PR has a test case which I am not including
because it is unlikely to keep exposing this behavior in the future.
