This code is very sensitive to the difference between "columns" as printed
and "bytes" (SourceManager columns). All variables are now named explicitly
and our assumptions are (hopefully) documented as both comment and assertion.

Whether parseable fixits should use byte offsets or Unicode character counts
is pending discussion on the mailing list; currently the implementation uses
bytes (and has no problems on lines containing multibyte characters).
This has been added to the user manual.

CmpRuns can be used for static analyzer bug report comparison. However,
we want to make sure external users do not rely on the way bugs are
represented (plist files). Make sure that we have a user
friendly/documented API for CmpRuns script.

This function has two versions. The first one is used for a register operand.
The second one is used for an immediate number.

being a property of a canonical type to being a property of the fully-sugared

ignores one of its parameters, and that parameter is an unexpanded parameter
pack.

struct __attribute__((visibility("hidden"))) zed {
};
struct __attribute__((visibility("hidden"))) zed;

Which is a bit silly and got a lot noisier now that we correctly handle
visibility pragmas. This patch fixes that and also has some extra quality
improvements:

* We now produce an error instead of a warning for

struct __attribute__((visibility("hidden"))) zed {
};
struct __attribute__((visibility("default"))) zed;

* The "after definition" warning now points to the new attribute that is
  ignored instead of pointing to the declaration.

instead push the terminator for the branch down into the basic blocks of the subexpressions of '&&' and '||'
respectively.  This eliminates some artifical control-flow from the CFG and results in a more
compact CFG.

Note that this patch only alters the branches 'while', 'if' and 'for'.  This was complex enough for
one patch.  The remaining branches (e.g., do...while) can be handled in a separate patch, but they
weren't immediately tackled because they were less important.

It is possible that this patch introduces some subtle bugs, particularly w.r.t. to destructor placement.
I've tried to audit these changes, but it is also known that the destructor logic needs some refinement
in the area of '||' and '&&' regardless (i.e., their are known bugs).

inferred from its size.  Thus, very large vectors will be over-aligned with no 
benefit.  Target owners should set this target max.
