ArchDefaultUnwindPlan plug-in interfaces are now cached per architecture 
instead of being leaked for every frame.

Split the ArchDefaultUnwindPlan_x86 into ArchDefaultUnwindPlan_x86_64 and
ArchDefaultUnwindPlan_i386 interfaces.

There were sporadic crashes that were due to something leaking or being 
destroyed when doing stack crawls. This patch should clear up these issues.

Simplify the spill weight calculation a bit by bypassing
getApproximateInstructionCount() and using LiveInterval::getSize() directly.
This changes the computed spill weights, but only by a constant factor in each
function. It should not affect how spill weights compare against each other, and
so it shouldn't affect code generation.

  various types and numbers of arguments rather than trying to keep a
  constant number of arguments for all the types.

- Also create a Register type within the instructions, to hold
  register type and number.

- Modify EmulateInstructionArm.cpp to use the new register and context
  types in all the instruction emulation functions.

- Add code to emulate the STM Arm instruction.

during evaluate instruction, we flush out the change into m_inst_cpsr in preparation for the next

-Checkers will be defined in the tablegen file 'Checkers.td'.
-Apart from checkers, we can define checker "packages" that will contain a collection of checkers.
-Checkers can be enabled with -analyzer-checker=<name> and disabled with -analyzer-disable-checker=<name> e.g:
	Enable checkers from 'cocoa' and 'corefoundation' packages except the self-initialization checker:
	-analyzer-checker=cocoa -analyzer-checker=corefoundation -analyzer-disable-checker=cocoa.SelfInit
-Introduces CheckerManager and CheckerProvider. CheckerProviders get the set of checker names to enable/disable and
 register them with the CheckerManager which will be the entry point for all checker-related functionality.

Currently only the self-initialization checker takes advantage of the new mechanism.
