before issuing API calls to find the global variable and to get its value.
rdar://problem/9700873 has been updated to reflect the latest status. The dwarf case
now does not seg fault if the inferior is not started; instead, for dwarf case, the
value retrieved from the global variable is None.

Manage Inits in a FoldingSet. This provides several benefits:
- Memory for Inits is properly managed
- Duplicate Inits are folded into Flyweights, saving memory
- It enforces const-correctness, protecting against certain classes
of bugs
The above benefits allow Inits to be used in more contexts, which in
turn provides more dynamism to TableGen. This enhanced capability
will be used by the AVX code generator to a fold common patterns
together.

The enum names as well as order (i.e. value)
had skewed, which means that consumers of the
tablegen-ed table would see different values than
intended. Make both files have a superset of enums,
and add classification as needed for numMCOperands.

Print shifted immediate values directly rather than as a payload+shifter
value pair. This makes for more readable output assembly code, simplifies
the instruction printer, and is consistent with how Thumb immediates are
displayed.

type system. However most of these modifications were due to IRBuilder
(IRBuilderBase), not having been modified to NOT return such const qualified
free types. If IRBuilder does not change, as can also be seen in its
instruction creation methods, to use const free types, it may be useful to have
ExceptionDemo drop IRBuilder usage. Modifying builder.getInt32Ty() to
llvm::Type::getInt32Ty(builder.getContext()) is pretty ugly.

- an off-by-one error in emission of irregular array limits for
InitListExprs
- use an EH partial-destruction cleanup within the normal
array-destruction cleanup
- get the branch destinations right for the empty check
Also some refactoring which unfortunately obscures these changes.

with the "target modules lookup --address <addr>" command. The variable
ID's, names, types, location for the address, and declaration is
displayed.
This can really help with crash logs since we get, on MacOSX at least,
the registers for the thread that crashed so it is often possible to
figure out some of the variable contents.

and MCSubtargetInfo.
- Added methods to update subtarget features (used when targets automatically
detect subtarget features or switch modes).
- Teach X86Subtarget to update MCSubtargetInfo features bits since the
MCSubtargetInfo layer can be shared with other modules.
- These fixes .code 16 / .code 32 support since mode switch is updated in
MCSubtargetInfo so MC code emitter can do the right thing.

use lldb_private::Target::ReadMemory(...) to allow constant strings
to be displayed in global variables prior on in between process
execution.
Centralized the variable declaration dumping into:
bool
Variable::DumpDeclaration (Stream *s, bool show_fullpaths, bool show_module);
Fixed an issue if you used "target variable --regex <regex>" where the
variable name would not be displayed, but the regular expression would.
Fixed an issue when viewing global variables through "target variable"
might not display correctly when doing DWARF in object files.

is called whenever a tag type is completed. We previously used that
as the sign to layout the codegen representation for the tag type,
which worked but meant that we laid out *every* completed type, whether
it was used or not.
Now we just lay out the type if we've already seen it somehow else.
This means that we lay out types we've used but haven't seen a body
for, but we don't lay out tons of stuff that noone cares about.

caused us to skip layout out a function accurately. If
so, flush the type cache for both the function and struct
case to ensure that any pointers to the functions get
recomputed. This is overconservative, but with this patch
clang can build itself again.

conservative when converting a functiontype to IR when in a "pointer within
a struct" context. This has the unfortunate sideeffect of compiling all
function pointers inside of structs into "{}*" which, though correct, is
ugly. This has the positive side effect of being correct, and it is pretty
straight-forward to improve on this.
