3d9afa8e97 Fix PR14548: SROA was crashing on a mixture of i1 and i8 loads and stores.
When SROA was evaluating a mixture of i1 and i8 loads and stores, in
just a particular case, it would tickle a latent bug where we compared
bits to bytes rather than bits to bits. As a consequence of the latent
bug, we would allow integers through which were not byte-size multiples,
a situation the later rewriting code was never intended to handle.

In release builds this could trigger all manner of oddities, but the
reported issue in PR14548 was forming invalid bitcast instructions.

The only downside of this fix is that it makes it more clear that SROA
in its current form is not capable of handling mixed i1 and i8 loads and
stores. Sometimes with the previous code this would work by luck, but
usually it would crash, so I'm not terribly worried. I'll watch the LNT
numbers just to be sure.

f81093a826 Drop the address space limit for tests in the makefile build.
The limit seems to break newer pythons (see PR13598) so just drop it for now.
Eventually lit should learn to set limits for its children instead of a global
limit in the makefile.

If some PPC bots fail after this change: That's a good thing, they actually run
clang tests now.

f62b9cd890 Add the `lto_codegen_set_export_dynamic' function.
This function sets the `_exportDynamic' ivar. When that's set, we export all
symbols (e.g. we don't run the internalize pass). This is equivalent to the
`--export-dynamic' linker flag in GNU land:

--export-dynamic
  When creating a dynamically linked executable, add all symbols to the dynamic
  symbol table. The dynamic symbol table is the set of symbols which are visible
  from dynamic objects at run time. If you do not use this option, the dynamic
  symbol table will normally contain only those symbols which are referenced by
  some dynamic object mentioned in the link. If you use dlopen to load a dynamic
  object which needs to refer back to the symbols defined by the program, rather
  than some other dynamic object, then you will probably need to use this option
  when linking the program itself.

The Darwin linker will support this via the `-export_dynamic' flag. We should
modify clang to support this via the `-rdynamic' flag.

550f0ade45 Make the contents of encoded sections SmallVector<char, N> instead of
SmallString. This makes it possible to use the length-erased SmallVectorImpl
in the interface without imposing buffer size. Thus, the size of MCInstFragment
is back down since a preallocated 8-byte contents buffer is enough.

It would be generally a good idea to rid all the fragments of SmallString as
contents, because a vector just makes more sense.

6eb3e87df0 Added Mapping Symbols for ARM ELF
Before this patch, when you objdump an LLVM-compiled file, objdump tried to
decode data-in-code sections as if they were code.  This patch adds the missing
Mapping Symbols, as defined by "ELF for the ARM Architecture" (ARM IHI 0044D).

Patch based on work by Greg Fitzgerald.

f722b007b2 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.

ece6db5f16 [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).

06180bf3f2 Use the new MIBundleBuilder class in the Mips target.
This is the preferred way of creating bundled machine instructions.

c8ce7a4bb5 Add an MIBundleBuilder class.
Like the MachineInstrBuilder, this class makes it easier to build
bundles of MachineInstrs.

fad649a5b1 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().
