53185e9016 Add support for tsan annotations (thread sanitizer, a valgrind-based tool). 
These annotations are disabled entirely when either ENABLE_THREADS is off, or
building a release build. When enabled, they add calls to functions with no
statements to ManagedStatic's getters.

Use these annotations to inform tsan that the race used inside ManagedStatic
initialization is actually benign. Thanks to Kostya Serebryany for helping
write this patch!

0638353f56 Implement comparison operators for BranchProbability in a way that can't overflow INT64_MAX. 
Add a test case for the edge case that triggers this. Thanks to Chandler for bringing this to my attention.

c7c5395326 unittests/Support/DataExtractorTest.cpp: Specify ULL explicitly to a few constants.

fcc23eeec7 Add the DataExtractor utility class. 
It is an endian-aware helper that can read data from a StringRef. It will
come in handy for DWARF parsing. This class is inspired by LLDB's
DataExtractor, but is stripped down to the bare minimum needed for DWARF.

Comes with unit tests!

a78433a090 Make TypeBuilder's result depend on the LLVMContext it's passed. 
TypeBuilder was using a local static variable to cache its result. This made it
ignore changes in its LLVMContext argument and always return a type constructed
from the argument to the first call.

729d642928 Now that googletest can print ConstantRange, use EXPECT_EQ when testing for 
equality. Prefer EXPECT_EQ(foo, Full) over EXPECT_TRUE(foo.isFullSet()) because
the former will print out the contents of the constant range that failed.

98f201632e split raw_os_ostream out to its own header and implementation file. This 
means that raw_ostream no longer has to #include <iosfwd>.  Nothing in llvm

e58499843b Fix off-by-one in llvm::Format::print. 
- This also shortens the Format.h implementation, and uses the print buffer
   fully (it was wasting a character).

 - This manifested as llvm-test failures, because one side effect was that
   raw_ostream would write garbage '\x00' values into the output stream if it
   happened that the string was at the end of the buffer. This meant that grep
   would report 'Binary file matches', which meant the silly pattern matching
   llvm-test eventually does would fail. Cute. :)

20848835bf To catch bugs like the one fixed in 
http://llvm.org/viewvc/llvm-project?view=rev&revision=78127, I'm changing the
ExecutionEngine's global mappings to hold AssertingVH<const GlobalValue>. That
way, if unregistering a mapping fails to actually unregister it, we'll get an
assert. Running the jit nightly tests didn't uncover any actual instances of
the problem.

This also uncovered the fact that AssertingVH<const X> didn't work, so I fixed
that too.

4c892c05ec Parameterize the BumpPtrAllocator over a slab allocator. It defaults to using 
malloc, so there should be no functional changes to other code.

These changes are necessary since I have plans to use this allocator in the JIT
memory manager, and it needs a special allocator.

I also added some tests which helped me pinpoint some bugs.

A full set is a constant range that represents any number. If you take the

than 5 would be umax's against a value which is at least 5.
