unexpected, so we can't rely on the AsmParsers HadError variable directly.

Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.
Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

- Each macro instantiation introduces a new buffer, and FindBufferForLoc() is
linear, so previously macro instantiation could be N^2 for some pathological
inputs.

Roman Divacky. I added the bits in MCDwarf.cpp and the test.

see the offsetof operator. Previously, we were matching something like MOVrm
in the front-end and later matching MOVrr in the back-end. This change makes
things more consistent. It also fixes cases where we can't match against a
memory operand as the source (test cases coming).

a memory operand. Retain this information and then add the sizing directives
to the IR. This allows the backend to do proper instruction selection.

*NamedDecl. In turn, build the expressions after we're finished parsing the
asm. This avoids a crasher if the lookup fails.

layer. Add the ParseMSInlineAsm() function, which is the new interface to
clang. Also expose the new MCAsmParserSemaCallback interface, which is used
by the back-end to do name lookup in Sema. Finally, remove the now defunct
APIs introduced in r165946.

inline assembly. For the time being, these will be called directly by clang.
However, in the near future I expect these to be sunk back into the MC layer
and more basic APIs (e.g., getClobbers(), getConstraints(), etc.) will be called
by clang.

the interface between the front-end and the MC layer when parsing inline
assembly. Unfortunately, this is too deep into the parsing stack. Specifically,
we're unable to handle target-independent assembly (i.e., assembly directives,
labels, etc.). Note the MatchAndEmitInstruction() isn't the correct
abstraction either. I'll be exposing target-independent hooks shortly, so this
is really just a cleanup.

Based on a patch by PaX Team.
Fixed assertion failures on non-Darwin and added additional test cases.

* wrap code blocks in \code ... \endcode;
* refer to parameter names in paragraphs correctly (\arg is not what most
people want -- it starts a new paragraph);
* use \param instead of \arg to document parameters in order to be consistent
with the rest of the codebase.

For some reason .lcomm uses byte alignment and .comm log2 alignment so we can't
use the same setting for both. Fix this by reintroducing the LCOMM enum.
I verified this against mingw's gcc.

- Darwin lied about not supporting .lcomm and turned it into zerofill in the
asm parser. Push the zerofill-conversion down into macho-specific code.
- This makes the tri-state LCOMMType enum superfluous, there are no targets
without .lcomm.
- Do proper error reporting when trying to use .lcomm with alignment on a target
that doesn't support it.
- .comm and .lcomm alignment was parsed in bytes on COFF, should be power of 2.
- Fixes PR13755 (.lcomm crashes on ELF).

Extracted from the Andy/PaX patch. I added the test.
