The function will refuse to use a register class with fewer registers
than MinNumRegs.  This can be used by clients to avoid accidentally
increase register pressure too much.

The default value of MinNumRegs=0 doesn't affect how constrainRegClass()
works.

ST->scanReachableSymbols() is creating a SubRegionMap (SRM) on every call since one SRM is created in each ScanReachableSymbols instance. Creating the object just once and calling only scan inside the loop gives ~ 14% speed up of the StaticAnalyzer run (Release+Asserts). 

Pull out the declaration of the ScanReachableSymbols so that it can be used directly. Document ProgramState::scanReachableSymbols() methods.

demo on how to use the llvm exception mechanism, this hack will shortly be 
changed to use the new 3.0 exception infrastructure. However for the time being

UpgradeExceptionHandling(...) function on < 3.0 exception handling code.

OpenCL 6.2.1 says: "Implicit conversions between built-in vector data types are
disallowed."  OpenCL 6.2.2 says: "Explicit casts between vector types are not
legal."  For example:

uint4 u = (uint4)(1);
int4 i = u; // invalid implicit conversion
int4 e = (int4)u; // invalid explicit conversion

shared pointers.

Changed the ExecutionContext over to use shared pointers for
the target, process, thread and frame since these objects can
easily go away at any time and any object that was holding onto
an ExecutionContext was running the risk of using a bad object.

Now that the shared pointers for target, process, thread and
frame are just a single pointer (they all use the instrusive
shared pointers) the execution context is much safer and still
the same size. 

Made the shared pointers in the the ExecutionContext class protected
and made accessors for all of the various ways to get at the pointers,
references, and shared pointers.

- AVX: as SSE2, but also supports the wider ymm vectors. (this is covered by the isTypeLegal check)
