Handle -D arguments ending in a backslash.

We translate these into #define directives; to preserve gcc-compatible
semantics (where the expanded macro includes the backslash), we add
an extra "\\\n" to the end of the synthesized "#define".

[frontend] Don't put a PCH/PTH filename into the set of includes in the preprocessor options;
since only one of them is allowed in command-line, process them separately.

Otherwise, if more than one is specified in the command-line, one is processed normally
and the others are going to be treated and included as header files.

Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

Where before it was only on x86_64 and ppc64, it's now
also defined on mips64 and nvptx64.

Preprocessor: add __BYTE_ORDER__ predefined macro

Preprocessor: add __BYTE_ORDER__ predefined macro

The __BYTE_ORDER__ predefined macro was added in GCC 4.6:
http://gcc.gnu.org/onlinedocs/gcc-4.6.0/cpp/Common-Predefined-Macros.html

It's used like the following:

#if __BYTE_ORDER__ == __ORDER_LITTLE_ENDIAN__
...
#elif __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__
...
#else
#error insane architecture like the pdp-11
#endif

There's a similar macro, __FLOAT_WORD_ORDER__, but it looks like it
mainly exist to accommodate fairly obscure architectures and ARM's
old FPA instructions, so it doesn't seem nearly as useful.

The tests are updated to check for the correct(at least, based on
clang's current output) value of the macro on each target. So now the
suite will catch bugs like the one fixed in r157626.

Restructure how the driver communicates information about the
target Objective-C runtime down to the frontend: break this
down into a single target runtime kind and version, and compute
all the relevant information from that. This makes it
relatively painless to add support for new runtimes to the
compiler. Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z,
available at the driver level as a better and more general
alternative to -fgnu-runtime and -fnext-runtime. This new
concept of an Objective-C runtime also encompasses what we
were previously separating out as the "Objective-C ABI", so
fragile vs. non-fragile runtimes are now really modelled as
different kinds of runtime, paving the way for better overall
differentiation.

As a sort of special case, continue to accept the -cc1 flag
-fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak.

I won't go so far as to say "no functionality change", even
ignoring the new driver flag, but subtle changes in driver
semantics are almost certainly not intended.

More doxygen/documentation cleanups.

This reduces the number of warnings generated by Doxygen by about 100
(roughly 10%). Issues addressed:
(1) Primarily, backslash-escaped "@foo" and "#bah" in Doxygen comments
when they're not supposed to be Doxygen commands or links, and
similarly for "<baz>" when it's not intended as as HTML tag;
(2) Changed some \t commands (which don't exist) to \c ("to refer to a
word of code", as the Doxygen manual says);
(3) \precondition becomes \pre;
(4) When touching comments, deleted a couple of spurious spaces in them;
(5) Changed some \n and \r to \\n and \\r;
(6) Fixed one tiny typo: #pragms -> #pragma.

This patch touches documentation/comments only.
