ModuleManager::visit() by keeping a free list of the two data
structures used to store state (a preallocated stack and a visitation
number vector). Improves -fsyntax-only performance for my modules test
case by 2.8%. Modules has pulled ahead by almost 10% with the global
module index.

This would be against the style guide:
http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml?showone=Function_Declarations_and_Definitions#Function_Declarations_and_Definitions

Not sure what to do as a last resort if the function signature does not
fit onto a single line in Google style ..

better job with them. Shaves off 0.7% of -fparse-only time for a
modules test case. Sure makes you wonder...

Before we did not really systematically format those. Now, we format the
different cases as:

- 1 Line:  a ? b : c;
- 2 Lines: short ? loooooooooong
                 : loooooooooong
- 2 Lines: loooooooooooooooong
               ? short : short
- 3 Lines: loooooooooooooooong
               ? loooooooooooooong
               : loooooooooooooong

Not sure whether "?" and ":" should go on the new line, but it seems to
be the most consistent approach.

It is way too slow. Change the default option value to 0.
Always do exact shadow propagation for unsigned ICmp with constants, it is
cheap (under 1% cpu time) and required for correctness.

1. Use a hanging ident for function calls nested in binary expressions.
   E.g.:
   int aaaaa = aaaaaaaaa && aaaaaaaaaa(
                                aaaaaaaaaa);

2. Slightly improve heuristic for builder type expressions and reduce
   penalty for breaking before "." and "->" in those.

3. Remove  mostly obsolete metric of decreasing indent level. This
   fixes: llvm.org/PR14931.

Changes #1 and #2 were necessary to keep tests passing after #3.

These always represent a continuation and we should increase the ident.

A bugfix for tblgen, in the function ‘emitSourceFileHeader’.
When the first parameter (‘Desc’) is more than 80 characters long, it will result the header line that contains the description to be more
Than (4GB!) long. Not only it takes forever to produce, the output file cannot be open, since its ginormous.

Patch by Elior Malul.

Created ObjCARCUtil.cpp for functions which in my humble opinion are too large to static inline and place in a header file such as ObjCARC.h.

This now uses the AttributeSet object instead of the Attribute /
AttributeWithIndex objects. It's fairly simple now. It goes through all of the
subsets before the one we're modifying, adds them to the new set. It then adds
the modified subset (with the requested attributes removed). And then adds the
rest of the subsets.
