now that this handles the release / retain calls.

Adds a regression test for that bug (which is a compile-time
regression) and for the last two changes to the IntrusiveRefCntPtr,
especially tests for the memory leak due to copy construction of the
ref-counted object and ensuring that the traits are used for release /
retain calls.

BitVector uses the native word size for its internal representation.
That doesn't work well for literal bit masks in source code.

This patch adds BitVector operations to efficiently apply literal bit
masks specified as arrays of uint32_t.  Since each array entry always
holds exactly 32 bits, these portable bit masks can be source code
literals, probably produced by TableGen.

Move to a by-section allocation and relocation scheme. This allows
better support for sections which do not contain externally visible
symbols.

Flesh out the relocation address vs. local storage address separation a
bit more as well. Remote process JITs use this to tell the relocation
resolution code where the code will live when it executes.

The startFunctionBody/endFunctionBody interfaces to the JIT and the
memory manager are deprecated. They'll stick around for as long as the
old JIT does, but the MCJIT doesn't use them anymore.

is testing the bitcode reader's functionality, not VMCore's. Add the
what is a hope sufficient build system mojo to build and run a new
unittest.

Also clean up some of the test's naming. The goal for the file should be
to unittest the Bitcode Reader, and this is just one particular test
among potentially many in the future. Also, reverse my position and
relegate the PR# to a comment, but stash the comment on the same line as
the test name so it doesn't get lost. This makes the code more
self-documenting hopefully w/o losing track of the PR number.

build. This didn't show up in the CMake build because the CMake build
for the unittests is rather poorly factored.

This probably isn't the correct fix. This should be a bitcode reader
unittest not a VMCore unittest. I'll move it and clean various parts of
the unittest up in a follow-up patch, but I wanted to unbreak the bots.

Diagnostics are now emitted via the SourceMgr and we use MemoryBuffer
for buffer management. Switched the code to make use of the trailing
'0' that MemoryBuffer guarantees where it makes sense.

make VariadicFunction actually be trivial. Do so, and also make it look
more like your standard trivial functor by making it a struct with no
access specifiers. The unit test is updated to initialize its functors
properly.

variadic-like functions in C++98. See the comments in the header file
for a more detailed description of how these work. We plan to use these
extensively in the AST matching library. This code and idea were
originally authored by Zhanyong Wan. I've condensed it using macros
to reduce repeatition and adjusted it to fit better with LLVM's ADT.

Thanks to both David Blaikie and Doug Gregor for the review!

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!

the X86 asmparser to produce ranges in the one case that was annoying me, for example:

test.s:10:15: error: invalid operand for instruction
movl 0(%rax), 0(%edx)
              ^~~~~~~

It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use 
ranges where appropriate if someone is interested.

Based on Horspool's simplified version of Boyer-Moore. We use a constant-sized table of
uint8_ts to keep cache thrashing low, needles bigger than 255 bytes are uncommon anyways.

The worst case is still O(n*m) but we do a lot better on the average case now.
