docs: Convert LangRef to reST.
NOTE: If you have any patches in the works that modify LangRef, you will
need to rewrite the changes to LangRef.html to their equivalents in
LangRef.rst. If you need assistance feel free to contact me.
Since LangRef is mission-critical for the project and "normative", I
have taken extra care to ensure that no content was lost or altered in
the conversion. The content was converted with a tool called `pandoc`,
so there is no chance for a human error like accidentally forgetting a
sentence or whatever. After the initial conversion by `pandoc`, only
changes to the markup were done.
This is just the most literal conversion of the HTML document as
possible. It might be worth exploring some way to chop up this massive
document into separate pages, e.g. something like
`docs/LangRef/Instructions.rst`, `docs/LangRef/Intrinsics.rst`, etc.
with `docs/LangRef.rst` being an "intro/navigation page" of sorts. On
the other hand, that loses the ability to {Ctrl,Cmd}-F for a given term
right from your browser.
IMO, I think our stylesheet needs some work because I find it hard to
tell what level of nesting some of the headings are at (e.g. "is this a
new section or is it a subsection?"). The issue is present on other
pages, but the sheer size and deep section structure of LangRef really
brings this issue out. If there are any web designers out there in the
community it would be awesome if you tried to come up with something
nicer.

[msan] Remove readonly/readnone attributes from all called functions.
MSan uses a TLS slot to pass shadow for function arguments and return values.
This makes all instrumented functions not readonly, and at the same time
requires that all callees of an instrumented function that may be
MSan-instrumented do not have readonly attribute (otherwise some of the
instrumentation may be optimized out).

Add higher-level API for dealing with bundled MachineInstrs.
This is still a work in progress. The purpose is to make bundling and
unbundling operations explicit, and to catch errors where bundles are
broken or created inadvertently.
The old IsInsideBundle flag is replaced by two MI flags: BundledPred
which has the same meaning as IsInsideBundle, and BundledSucc which is
set on instructions that are bundled with a successor. Having two flags
provdes redundancy to detect when a bundle is inadvertently torn by a
splice() or insert(), and it makes it possible to write bundle iterators
that don't need to peek at adjacent instructions.
The new flags can't be manipulated directly (once setIsInsideBundle is
gone). Instead there are MI functions to make and break bundle bonds.
The setIsInsideBundle function will be removed in a future commit. It
should be replaced by bundleWithPred().

Add support to ValueTracking for determining that a pointer is non-null
by virtue of inbounds GEPs that preclude a null pointer.
This is a very common pattern in the code generated by std::vector and
other standard library routines which use allocators that test for null
pervasively. This is one step closer to teaching Clang+LLVM to be able
to produce an empty function for:
void f() {
std::vector<int> v;
v.push_back(1);
v.push_back(2);
v.push_back(3);
v.push_back(4);

push_back sequences into constants when inlining and other optimizations

[msan] Do not store origin for clean values.
Instead of unconditionally storing origin with every application store,
only do this when the shadow of the stored value is != 0.
This change also delays instrumentation of stores until after the walk over
function's instructions, because adding new basic blocks confuses InstVisitor.
We only keep 1 origin value per 4 bytes of application memory. This change
fixes the bug when a store of a single clean byte wiped the origin for the
whole 4-byte area.
Since stores of uninitialized values are relatively uncommon, this change
improves performance of track-origins mode by 5% median and by up to 47% on

Let targets provide hooks that compute known zero and ones for any_extend

zero-extend, then this can enable more demanded bits optimizations. e.g.
define void @foo(i16* %ptr, i32 %a) nounwind {
entry:
%tmp1 = icmp ult i32 %a, 100
br i1 %tmp1, label %bb1, label %bb2
bb1:
%tmp2 = load i16* %ptr, align 2
br label %bb2
bb2:

br i1 %cmp, label %bb3, label %exit
bb3:
call void @bar() nounwind
br label %exit

docs: Sphinxify `docs/tutorial/`
Sorry for the massive commit, but I just wanted to knock this one down
and it is really straightforward.
There are still a couple trivial (i.e. not related to the content)
things left to fix:
- Use of raw HTML links where :doc:`...` and :ref:`...` could be used
instead. If you are a newbie and want to help fix this it would make
for some good bite-sized patches; more experienced developers should
be focusing on adding new content (to this tutorial or elsewhere, but
please _do not_ waste your time on formatting when there is such dire
need for documentation (see docs/SphinxQuickstartTemplate.rst to get
started writing)).
- Highlighting of the kaleidoscope code blocks (currently left as bare
`::`). I will be working on writing a custom Pygments highlighter for
this, mostly as training for maintaining the `llvm` code-block's lexer
in-tree. I want to do this because I am extremely unhappy with how it
just "gives up" on the slightest deviation from the expected syntax
and leaves the whole code-block un-highlighted.
More generally I am looking at writing some Sphinx extensions and
keeping them in-tree as well, to support common use cases that
currently have no good solution (like "monospace text inside a link").

Reapply r160148 (reverted in r163570) fixing spurious breakpoints in modern GDB
This reapplies the fix for PR13303 now with more justification. Based on my
execution of the GDB 7.5 test suite this results in:
expected passes: 16101 -> 20890 (+30%)
unexpected failures: 4826 -> 637 (-77%)
There are 23 checks that used to pass and now fail. They are all in
gdb.reverse. Investigating a few looks like they were accidentally passing
due to extra breakpoints being set by this bug. They're generally due to the
difference in end location between gcc and clang, the test suite is trying to
set breakpoints on the closing '}' that clang doesn't associate with any
instructions.

Make NaCl naming consistent. The triple OSType is called NaCl and is represented
textually as NativeClient. Also added a link to the native client project for
readers unfamiliar with it.
A Clang patch will follow shortly.
