Nuke the hilariously out of date suggestion to unpack llvm-gcc 4.2 as
part of getting started with LLVM.
The LLVM getting started document is in woeful need of attention. I may
get to some of this, but some random notes for folks interested:
1) We need to separate the getting started steps for folks who are
interested in the core LLVM libs and nothing else, folks interested
in a nifty C++ toolchain and nothing else, and folks interested in
both.
2) We should include documentation for both release archives, svn, and
git in equal portion, and we should document all of the various
repositories of interest: llvm, clang, clang-tools-extra,
compiler-rt, lld, libcxx, test-suite.
3) We should document the CMake build. We should probably document the
CMake build first, and give a fall-back set of docs for the Makefile
build for the use cases where that is still the preferred solution.
This would more closely match the use cases that folks in the open
source community are likely to have, and would remove a point of
discrepancy between Linux, Windows, and Mac instructions.
4) Probably a ton of other modernization stuff that I've not thought of
here.

[conf] Add config variable to disable crash related overrides.
- We do some nasty things w.r.t. installing or overriding signal handlers in
order to improve our crash recovery support or interaction with crash
reporting software, and those things are not necessarily appropriate when
LLVM is being linked into a client application that has its own ideas about
how to do things. This gives those clients a way to disable that handling at
build time.
- Currently, the code this guards is all Apple specific, but other platforms
might have the same concerns so I went for a more generic configure
name. Someone who is more familiar with library embedding on Windows can
handle choosing which of the Windows/Signals.inc behaviors might make sense
to go under this flag.
- This also fixes the proper autoconf'ing of ENABLE_BACKTRACES. The code
expects it to be undefined when disabled, but the autoconf check was just
defining it to 0.

Fix a problem with dual mips16/mips32 mode. When the underlying processor
has hard float, when you compile the mips32 code you have to make sure
that it knows to compile any mips32 routines as hard float. I need to clean
up the way mips16 hard float is specified but I need to first think through
all the details. Mips16 always has a form of soft float, the difference being
whether the underlying hardware has floating point. So it's not really
necessary to pass the -soft-float to llvm since soft-float is always true
for mips16 by virtue of the fact that it will not register floating point
registers. By using this fact, I can simplify the way this is all handled.

[PowerPC] Add loads, stores, and related things to fast-isel.
This is the next big chunk of fast-isel code. The primary purpose is
to implement selection of loads and stores, but there is a lot of
drag-along to support this. The common code to analyze addresses for
both loads and stores is substantial. It's also necessary to add the
materialization code for global values.
Related to load-store processing is the code to fold loads into
integer extends, since otherwise we generate lots of redundant
instructions. We also need to add some overrides to some FastEmit
routines to ensure we don't assign GPR 0 to a virtual register when
this would change the meaning of an instruction.
I added handling selection of a few binary arithmetic instructions, to
enable committing some test cases I wrote a while back.
Finally, ap couple of miscellaneous changes:
* I cleaned up some poor style from a previous patch in
PPCISelLowering.cpp, pointed out by David Blaikie.
* I enlarged the Addr.Offset field to avoid sign problems with 32-bit

Change default # of digits for APFloat::toString
This is a re-commit of r189442; I'll follow up with clang changes.
The previous default was almost, but not quite enough digits to
represent a floating-point value in a manner which preserves the
representation when it's read back in. The larger default is much
less confusing.
I spent some time looking into printing exactly the right number of
digits if a precision isn't specified, but it's kind of complicated,
and I'm not really sure I understand what APFloat::toString is supposed
to output for FormatPrecision != 0 (or maybe the current API specification
is just silly, not sure which). I have a WIP patch if anyone is interested.
