sys::process::get_id() now returns the process ID instead of a process handle on Windows.  Patch thanks to Kim Gräsman!

Fix the parser's updating of the template depth when parsing local templates and late-parsed templates. 
This is a slight tweak of r180708; It avoids incrementing depth when non-template local classes nested within member templates of local classes are encountered.  
This patch was LGTM'd by Doug http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20130506/079656.html and passed the regression tests that normally pass (i.e. excluding many Module and Index tests on Windows that fail regardless)

I ran clang-format on my patch but it seemed to have wreaked havoc with new lines  - might have to do with using it on windows :( will resubmit once i've cleaned this issue up. sorry.

r183614 was failing because va_list on some platforms is defined in a
similar manner.  This test fails on Windows with r183614 applied.

This reverts commit r183614.

It broke test/Sema/block-printf-attribute-1.c on non-Windows platforms,
and the fix is not trivial.

This helps preserve the type-as-written in the AST, which we need for
MSVC mangling.  In particular, we need to preserve the types of array
parameters in function pointer types.

The essence of this change is:
-  QualType ArgTy = Param->getType();
+  QualType ArgTy = Param->getTypeSourceInfo()->getType();

... followed by the adjustment in ActOnFunctionDeclarator().

Several LLVM headers are moved.  The code listings in
LLVM tutorial are not updated yet.

This CL removes the code replica in the .rst, and replace
them with a literalinclude directive, so that sphinx can
include the latest code automatically.

  r183584 tries to derive some info from the code *AFTER* a call and apply
these derived info to the code *BEFORE* the call, which is not always safe
as the call in question may never return, and in this case, the derived
info is invalid.
  
  Thank Duncan for pointing out this potential bug.

We drew the diagnostic edges to wrong statements in cases the note was on a macro.
The fix is simple, but seems to work just fine for a whole bunch of test cases (plist-macros.cpp).

Also, removes an unnecessary edge in edges-new.mm, when function signature starts with a macro.

instantiation issue with non-standard type.

Add a backend option to warn on a given stack size limit.
Option: -mllvm -warn-stack-size=<limit>
Output (if limit is exceeded):
warning: Stack size limit exceeded (<actual size>) in <functionName>.

The longer term plan is to hook that to a clang warning.

This is using a hint from AMD APP OpenCL Programming Guide with
empirically tweaked parameters.
I used Unigine Heaven 3.0 to determine best parameters on my system
(i7 2600/Radeon 6950/Kernel 3.9.4) the benchmark :
it went from 38.8 average fps to 39.6, which is ~3% gain.
(Lightmark 2008.2 gain is much more marginal: from 537 to 539)

There is no lit test provided as the parameter were determined
empirically and it it would be nearly impossiblet to find a test
program that check for optimal behavior.

  The MemCpyOpt pass is capable of optimizing:
      callee(&S); copy N bytes from S to D.
    into:
      callee(&D);
subject to some legality constraints. 

  Assertion is triggered when the compiler tries to evalute "sizeof(typeof(D))",
while D is an opaque-typed, 'sret' formal argument of function being compiled.
i.e. the signature of the func being compiled is something like this:
  T caller(...,%opaque* noalias nocapture sret %D, ...)

  The fix is that when come across such situation, instead of calling some
utility functions to get the size of D's type (which will crash), we simply
assume D has at least N bytes as implified by the copy-instruction.

On PPC32, [su]div,rem on i64 types are transformed into runtime library
function calls. As a result, they are not allowed in counter-based loops (the
counter-loops verification pass caught this error; this change fixes PR16169).
