One more patch towards JIT support for Mips.

- Add TSFlags for the instruction formats. The idea here is to use

of the instructions (since Mips encodings are pretty straightforward)
- Improve the mips mechanism for compilation callback
- Add Mips specific code for invalidating the instruction cache
- Next patch will address wrong tablegen encoding

This patch adds support of NativeClient (*-*-nacl) OS support to LLVM.

The motivation for this change is to start upstreaming PNaCl work. The
whole set of patches include llvm backends (i686, x86_64, ARM),
llvm-gcc (probably, would not be upstreamed because it's deprecated)
and clang (the work has been just started, the amount of changes is
going to be low and the most of the work is expected to be done close
to the mainline).

screwy things by setting PWD != getcwd(). For example, some developers I know

output. With this patch, that trick will now work on clang too.
The only other effect of this change is that the static analysis will now
respect $PWD when reporting the directory of the files in its HTML output. I
think that's fine.

Move TargetRegistry.cpp from lib/Support to lib/Target where it belongs.
...
The header file was already properly located. The previous need for it
in Support had to do with the version string printing which was fixed in
r135757.
Also update build dependencies where libraries that needed the
functionality of the Target library (in the form of the TargetRegistry)
were picking it up via Support. This is pretty pervasive, essentially
every TargetInfo library (ARMInfo, etc) uses TargetRegistry, making it
depend on Target. All of these were previously just sneaking by.

Move the registered target printing in version strings completely out of
...
the Support library. Now its part of the TargetRegistry, and the three
commands that care about this explicitly register this extra bit of
version information.
The set of commands which care was computed by intersecting those which
use the Support library's version string printing and those that
initialize all the registered targets in a way that produces
a meaningful list. The only odd ball out is that 'clang -cc1as -version'
no longer prints the registered targets. I don't think anyone is really
interested in that (especially as the fact that llvm-mc does so is under
a FIXME), but if someone really does want this back I'll happily apply
the same patch there.

directly; a huge layering violation. This is the first step to hoisting
it out into the tools without adding lots of duplicated code.

Added *hidden* flags -print-options and -print-all-options so
...
developers can see if their driver changed any cl::Option's. The
current implementation isn't perfect but handles most kinds of
options. This is nice to have when decomposing the stages of
compilation and moving between different drivers. It's also a good
sanity check when comparing results produced by different command line
invocations that are expected to produce the comparable results.
Note: This is not an attempt to prolong the life of cl::Option. On the
contrary, it's a placeholder for a feature that must exist when
cl::Option is replaced by a more appropriate framework. A new
framework needs: a central option registry, dynamic name lookup,
non-global containers of option values (e.g. per-module,
per-function), *and* the ability to print options values and their defaults at
any point during compilation.

Assorted bugfixes in object file handling:
...
- Adds support for sniffing PE/COFF files on win32 (.exe and .dll)
which are COFF files that have an MS-DOS compatibility stub on
the front of them.
- Fixes a bug in the COFFObjectFile's support for the Microsoft COFF
extension for long symbol names, wherein it was attempting to parse
the leading '/' in an extended symbol name reference as part of the
integer offset.
- Fixes bugs in COFFObjectFile and ELFObjectFile wherein section
and symbol iterators were being returned with uninitialized bytes;
the type DataRefImpl is a union between 2 32-bit words (d.a and d.b)
and a single intptr_t word (p). Only p was being initialized, so in
32-bit builds the result would be iterators with random upper 32-bit
words in their DataRefImpls. This caused random failures when
seeking around in object files.

StringMap was not properly updating NumTombstones after a clear or rehash.
This was not fatal until now because the table was growing faster than
NumTombstones could, but with the previous change of preventing infinite

stopped being observed, causing infinite loops in certain situations.

Avoid turning a floating point division with a constant power of two into a denormal multiplication.
...
Some platforms may treat denormals as zero, on other platforms multiplication
with a subnormal is slower than dividing by a normal.

03fd672609
Add APFloat::getExactInverse.
...
The idea is, that if an ieee 754 float is divided by a power of two, we can
turn the division into a cheaper multiplication. This function sees if we can
get an exact multiplicative inverse for a divisor and returns it if possible.
This is the hard part of PR9587.
I tested many inputs against llvm-gcc's frotend implementation of this
optimization and didn't find any difference. However, floating point is the
land of weird edge cases, so any review would be appreciated.

raw_ostream: while it is generally desirable to do larger writes, it can lead to

The signed version of our "magic number" computation for the integer approximation
...
of a constant had a minor typo introduced when copying it from the book, which
caused it to favor negative approximations over positive approximations in many
cases. Positive approximations require fewer operations beyond the multiplication.
In the case of division by 3, we still generate code that is a single instruction
larger than GCC's code.

Clang was not parsing target triples involving EABI and was generating wrong IR (wrong PCS) and passing the wrong information down llc via the target-triple printed in IR.

...
On LLP64 Win64, 'states1' (for small version) was expanded to 'char *' for large version. Thus small version would be mischosen when nstates > 32 regardless of sizeof(long) on Win64.

Add ADT/IntervalMap.
...
This is a sorted interval map data structure for small keys and values with
automatic coalescing and bidirectional iteration over coalesced intervals.
Except for coalescing intervals, it provides similar functionality to std::map.
It is however much more compact for small keys and values, and hopefully faster
too.
The container object itself can hold the first few intervals without any
allocations, then it switches to a cache conscious B+-tree representation. A
recycling allocator can be shared between many containers, even between
containers holding different types.
The IntervalMap is initially intended to be used with SlotIndex intervals for:
- Backing store for LiveIntervalUnion that is smaller and faster than std::set.
- Backing store for LiveInterval with less overhead than std::vector for typical
intervals and O(N log N) merging of large intervals. 99% of virtual registers
need 4 entries or less and would benefit from the small object optimization.
- Backing store for LiveDebugVariable which doesn't exist yet, but will track
debug variables during register allocation.
This is a work in progress. Missing items are:
- Performance metrics.
- erase().
- insert() shrinkage.
- clear().
- More performance metrics.
- Simplification and detemplatization.
