Evan Cheng 7fae11b231 - Add MachineInstrBundle.h and MachineInstrBundle.cpp. This includes a function 
to finalize MI bundles (i.e. add BUNDLE instruction and computing register def
  and use lists of the BUNDLE instruction) and a pass to unpack bundles.
- Teach more of MachineBasic and MachineInstr methods to be bundle aware.
- Switch Thumb2 IT block to MI bundles and delete the hazard recognizer hack to
  prevent IT blocks from being broken apart.

Johnny Chen c6770763e6 http://llvm.org/bugs/show_bug.cgi?id=11560 lldb::SBTarget::FindFirstType crashes when passed None 
Add null checks to several functions.  Plus add test scenario for passing None to SBTarget.FindFirstType(None) and friends.

Sean Callanan fc4f2fb0da This commit is the result of a general audit of 
the expression parser to locate instances where
dyn_cast<>() and isa<>() are used on types, and
replace them with getAs<>() as appropriate.

The difference is that dyn_cast<>() and isa<>()
are essentially LLVM/Clang's equivalent of RTTI
-- that is, they try to downcast the object and
return NULL if they cannot -- but getAs<>() can
traverse typedefs to perform a semantic cast.

Anna Zaks 099fe3fb28 [analyzer] Treat stdin as a source of taint. 
Some of the test cases do not currently work because the analyzer core
does not seem to call checkers for pre/post DeclRefExpr visits.
(Opened radar://10573500. To be fixed later on.)

Richard Trieu 96ed5b6b47 Make the diagnostic message more consistant. Update the type comparison to 
handle non-pointer types.  This is for the extra info printed when function
