Using -mmacosx-version-min (etc.) on non-Darwin platforms should be a warning,
not a hard error. There is no reason to add a special check for these options
in the default toolchain. This just removes the special check and then we get
the usual -Wunused-command-line-argument warning if someone tries to use one
of these options for a target where they are not supported.

When registering a pass, a pass can now specify a second construct that takes as
argument a pointer to TargetMachine.
The PassInfo class has been updated to reflect that possibility.
If such a constructor exists opt will use it instead of the default constructor
when instantiating the pass.
Since such IR passes are supposed to be rare, no specific support has been
added to this commit to allow an easy registration of such a pass.
In other words, for such pass, the initialization function has to be
hand-written (see CodeGenPrepare for instance).
Now, codegenprepare can be tested using opt:
opt -codegenprepare -mtriple=mytriple input.ll

Adding a doxygen comment for each bit of API to indicate at which
LTO_API_VERSION each was available, manually gleaned from successive
git-blames. A few notes:
- LTO_API_VERSION was set to 3 at its introduction.
- I've indicated all the API introduced before LTO_API_VERSION was
around as available "prior to LTO_API_VERSION=3".
- A number of API changes neglected to bump LTO_API_VERSION. These I've
indicated as available at the *next* bump of LTO_API_VERSION.

Part 1 changes PlatformLinux::CreateInstance to always create with
is_host=false; that method is only used as the plug-in creator method
associated with the remote-linux platform plugin, and should therefore
always be remote.
Part 1 patch by Steve Pucci.
Part 2: fix a test break on linux.
In test/functionalities/thread/thread_specific_break, when using gcc,
either C99 mode would need to be enabled, or the code would need to
change. I changed a couple loop variable definitions to conform
to pre-C99 to simplify testing the fix. The second issue was
the necessity to include -lpthread as a linker option in the Makefile.
Any issues with that part are due to me (Todd Fiala).

The MSVC ABI is rather finicky about the exact representation of it's
pointer-to-member representation. The exact position of when and where
it will go with one representation versus another appears to be when it
desires the pointer-to-member to be complete.
To properly implement this in clang, do several things:
- Give up on tracking the polymorphic nature of the class. It isn't
useful to Sema and is only pertinent when choosing CodeGen-time
details like whether the field-offset can be 0 instead of -1.
- Insist on locking-in the inheritance model when we ask our
pointer-to-member type to be complete. From there, grab the
underlying CXXRecordDecl and try to make *that* complete. Once we've
done this, we can calculate it's inheritance model and apply it using
an attribute.
N.B. My first bullet point is a lie. We will eventually care about the
specifics of whether or not a CXXRecordDecl is or is not polymorphic
because MSVC compatible mangling of such things depends on it. However,
I believe we will handle this in a rather different way.

with raw_ostream's write_escaped() method.
For example darwin's otool(1) program that uses the llvm
disassembler now produces disassembly like this:
leaq 0x7b(%rip), %rdi ## literal pool for: "%f\ntoto\n"
and not print the new lines which messes up the output.

Citation: C++11 [expr.shift]p1 (and the equivalent text in C11).
This fixes PR18073, but the right thing to do (as noted in the FIXME) is to
have a real checker for too-large shifts.

Includes some style tweaks and removes the tautological observation that "Clang
is still under heavy development" -- it hopefully always will be.

Also shuffle the Communication section so the bug tracker comes first.
(The sidebar isn't scrollable at the moment so this gives a better chance of
the bug tracker being seen. The links further down are basically invisible --
we should look into that.)

This is necessary because the classes are shared between all implementations.
No functional change since the InstrItinData's have been duplicated.

This is necessary because the classes are shared between all schedulers.
Once this patch series is committed there will be an InstrItinClass for
each mnemonic with minimal grouping. This does increase the size of the
itinerary tables for each MIPS scheduler but we have a few options for dealing
with that later. These options include reducing the number of classes once
we see the best way to simplify them, or by extending tablegen to be able
to compress the table by eliminating duplicates entries, etc.

This change allows to compile sanitizer sources so that *san runtime
will attempt to use libbacktrace and/or libiberty for symbolization
(instead of communicating with llvm-symbolizer).
I've tested this patch by manually defining SANITIZER_LIBBACKTRACE and/or
SANITIZER_CP_DEMANGLE, linking with necessary libraries and verifying that
all tests from ASan test suite work.
Based on patches by Jakub Jelinek!

Affects:
DMULT, DMULTu, MADD, MADD_MM, MADDU, MADDU_MM, MSUB, MSUB_MM, MSUBU,
MSUBU_MM, MULT, MULTu
Does not affect MULT_MM, MULTu_MM since they are currently miscategorised
as IIImul.

Additionally, remove the optional nature of the spelling list index when creating attributes. This is supported by table generating a Spelling enumeration when the spellings for an attribute are distinct enough to warrant it.
