Saleem Abdulrasool 35476334e9 Support: split object format out of environment
This is a preliminary setup change to support a renaming of Windows target
triples.  Split the object file format information out of the environment into a
separate entity.  Unfortunately, file format was previously treated as an
environment with an unknown OS.  This is most obvious in the ARM subtarget where
the handling for macho on an arbitrary platform switches to AAPCS rather than
APCS (as per Apple's needs).

Ahmed Charles 56440fd820 Replace OwningPtr<T> with std::unique_ptr<T>.
This compiles with no changes to clang/lld/lldb with MSVC and includes
overloads to various functions which are used by those projects and llvm
which have OwningPtr's as parameters. This should allow out of tree
projects some time to move. There are also no changes to libs/Target,
which should help out of tree targets have time to move, if necessary.

Ben Langmuir 8d11639612 Fix an inconsistency in treatment of trailing / in path::const_iterator
When using a //net/ path, we were transforming the trailing / into a '.'
when the path was just the root path and we were iterating backwards.
Forwards iteration and other kinds of root path (C:\, /) were already
correct.

Ahmed Charles fba066461f [C++11] Add overloads for externally used OwningPtr functions.
This will allow external callers of these functions to switch over time
rather than forcing a breaking change all a once. These particular

Chandler Carruth b475b42a88 Hey, we can stop depending on the IR library from the Support unittests
now. ;] Tested on both a static and shared CMake build. Hopefully the

Chandler Carruth 4b6845c7e7 [Modules] Move the LeakDetector header into the IR library where the
source file had already been moved. Also move the unittest into the IR
unittest library.

This may seem an odd thing to put in the IR library but we only really
use this with instructions and it needs the LLVM context to work, so it
is intrinsically tied to the IR library.

Chandler Carruth 8cd041ef19 [Modules] Move the ConstantRange class into the IR library. This is
a bit surprising, as the class is almost entirely abstracted away from
any particular IR, however it encodes the comparsion predicates which
mutate ranges as ICmp predicate codes. This is reasonable as they're
used for both instructions and constants. Thus, it belongs in the IR
library with instructions and constants.

Chandler Carruth a4ea269f15 [Modules] Move ValueMap to the IR library. While this class does not
directly care about the Value class (it is templated so that the key can
be any arbitrary Value subclass), it is in fact concretely tied to the
Value class through the ValueHandle's CallbackVH interface which relies
on the key type being some Value subclass to establish the value handle
chain.

Ironically, the unittest is already in the right library.

Chandler Carruth 4220e9c154 [Modules] Move ValueHandle into the IR library where Value itself lives.
Move the test for this class into the IR unittests as well.

This uncovers that ValueMap too is in the IR library. Ironically, the
unittest for ValueMap is useless in the Support library (honestly, so
was the ValueHandle test) and so it already lives in the IR unittests.
Mmmm, tasty layering.

Chandler Carruth 8394857f43 [Modules] Move InstIterator out of the Support library, where it had no
business.

This header includes Function and BasicBlock and directly uses the
interfaces of both classes. It has to do with the IR, it even has that
in the name. =] Put it in the library it belongs to.

This is one step toward making LLVM's Support library survive a C++
modules bootstrap.

Rafael Espindola 248ac13975 Fix resetting the DataLayout in a Module.
No tool does this currently, but as everything else in a module we should be
able to change its DataLayout.

Most of the fix is in DataLayout to make sure it can be reset properly.

The test uses Module::setDataLayout since the fact that we mutate a DataLayout
is an implementation detail. The module could hold a OwningPtr<DataLayout> and
the DataLayout itself could be immutable.

Thanks to Philip Reames for pushing me in the right direction.

Rafael Espindola 90c7f1cc16 Replace the F_Binary flag with a F_Text one.
After this I will set the default back to F_None. The advantage is that
before this patch forgetting to set F_Binary would corrupt a file on windows.
Forgetting to set F_Text produces one that cannot be read in notepad, which
is a better failure mode :-)

Rafael Espindola 5c20ac0134 Simplify remove, create_directory and create_directories.
Before this patch they would take an boolean argument to say if the path
already existed. This was redundant with the returned error_code which is able
to represent that. This allowed for callers to incorrectly check only the
existed flag instead of first checking the error code.

Instead, pass in a boolean flag to say if the previous (non-)existence should be
an error or not.

Callers of the of the old simple versions are not affected. They still ignore
the previous (non-)existence as they did before.

Filip Pizlo d57124455b This test was failing on non-X86-64 platforms because stackmaps only work on X86-64.

Filip Pizlo c95bd8d88f Stackmaps are used for OSR exits, which is a custom kind of unwinding. Hence, they
should not be marked nounwind.

Marking them nounwind caused crashes in the WebKit FTL JIT, because if we enable 
sufficient optimizations, LLVM starts eliding compact_unwind sections (or any unwind 
data for that matter), making deoptimization via stackmaps impossible.

This changes the stackmap intrinsic to be may-throw, adds a test for exactly the 
sympton that WebKit saw, and fixes TableGen to handle un-attributed intrinsics.

Thanks to atrick and philipreames for reviewing this.

Eric Christopher 420569be04 Add support for hashing attributes with DW_FORM_block. This required
passing down an AsmPrinter instance so we could compute the size of
the block which could be target specific. All of the test cases in
the unittest don't have any target specific data so we can use a NULL
AsmPrinter there. This also depends upon block data being added as
integers.

We can now hash the entire fission-cu.ll compile unit so turn the
flag on there with the hash value.
