55876621c9 Revert r148686 (and r148694, a fix to it) due to a serious layering 
violation -- MC cannot depend on CodeGen.

Specifically, the MCTargetDesc component of each target is actually
a subcomponent of the MC library. As such, it cannot depend on the
target-independent code generator, because MC itself cannot depend on
the target-independent code generator. This change moved a flag from the
ARM MCTargetDesc file ARMMCAsmInfo.cpp to the CodeGen layer in
ARMException.cpp, leaving behind an 'extern' to refer back to it. That
layering order isn't viable givin the constraints outlined above.
Commandline flags are designed to be static specifically to avoid these
types of bugs.

Fixing this is likely going to require some non-trivial refactoring.

cafc52ba9a Changing bitfield enums to unsigned ints. 
This was suggested by Chandler Carruth on the basis of past experience with
esoteric compilers/quirks relating to signed enums.

860d90844c start the implementation of a new ConstantDataVector and ConstantDataArray 
classes, per PR1324.  Not all of their helper functions are implemented,
nothing creates them, and the rest of the compiler doesn't handle them yet.

0c22143732 Simplify llvm:🆑:Option by using a bit field instead of manual bit packing. 
This still preserves the same total layout.

Previously it looked like:
*** Dumping AST Record Layout
   0 | class llvm:🆑:Option
   0 |   (Option vtable pointer)
   8 |   int NumOccurrences
  12 |   int Flags
  16 |   unsigned int Position
  20 |   unsigned int AdditionalVals
  24 |   class llvm:🆑:Option * NextRegistered
  32 |   const char * ArgStr
  40 |   const char * HelpStr
  48 |   const char * ValueStr
  sizeof=56, dsize=56, align=8
  nvsize=56, nvalign=8

Now it looks like:
*** Dumping AST Record Layout
   0 | class llvm:🆑:Option
   0 |   (Option vtable pointer)
   8 |   int NumOccurrences
  12 |   enum NumOccurrencesFlag Occurrences
  12 |   unsigned int Value
  12 |   enum OptionHidden HiddenFlag
  12 |   enum FormattingFlags Formatting
  13 |   unsigned int Misc
  16 |   unsigned int Position
  20 |   unsigned int AdditionalVals
  24 |   class llvm:🆑:Option * NextRegistered
  32 |   const char * ArgStr
  40 |   const char * HelpStr
  48 |   const char * ValueStr
  sizeof=56, dsize=56, align=8
  nvsize=56, nvalign=8

6d71b145da convert CAZ, UndefValue, and CPN to use DenseMap's again, this time without 
using OwningPtr.  OwningPtr would barf when the densemap had to reallocate,
which doesn't appear to happen on the regression test suite, but obviously
happens in real life :)

bffa428d01 An option to selectively enable parts of ARM EHABI support. 
This change adds an new value to the --arm-enable-ehabi option that
disables emitting unwinding descriptors. This mode gives a working
backtrace() without the (currently broken) exception support.

54e62d71e0 Make Value::isDereferenceablePointer() handle unreachable code blocks. (This 
returns false in the event the computation feeding into the pointer is
unreachable, which maybe ought to be true -- but this is at least consistent
with undef->isDereferenceablePointer().) Fixes PR11825!
