[-Wunreachable-code] Tweak heuristic for configuration values to include arithmetic operations involving sizeof(), but not raw integers.

This case was motivated by a false positive with the
llvm::AlignOf<> specialization in LLVM.

[C++11] Replacing Decl iterators attr_begin() and attr_end() with iterator_range attrs(). Updating all of the usages of the iterators with range-based for loops.

This is a reapplication of r203236 with modifications to the definition of attrs() and following the new style guidelines on auto usage.

memcpy cannot be passed NULL.  Ensuring that the destination pointer is non-NULL
requires checking success.  Rather than performing the success check at that
point, increasing indentation an additional level, fold it into the previous
statement.

strcmp cannot be passed a NULL.  Add a short-circuiting check to avoid the
possible API misuse.

It seems that the original commit missed the curly braces for the scope, always
doing the string comparision.

[C++11] Replacing RecordDecl iterators field_begin() and field_end() with iterator_range fields(). Updating all of the usages of the iterators with range-based for loops.

Adding range-based STL-like helper APIs. llvm::distance() is the range version of std::distance. llvm::copy is the range version of std::copy.

relevant subclasses of RuntimeDyldImpl. This allows construction of
RuntimeDyldImpl instances to be deferred until after the target architecture is
known.

Reapplying r203299 in a slightly different manner. Now range APIs are implemented in terms of iterator APIs.

De-virtualize a method since it doesn't override anything (yay 'override' keyword) and its class is in an anonymous namespace.

Some of the buildbots need to be upgraded to a more recen version of
dwarfdump first.

Reverting for now.

This can possibly be refined later, but right now the experience
is so incomprehensible for a user to understand what is going on
this isn't a useful warning.

An option with the same name already exists in the makefile build.

The name CLANG_IS_PRODUCTION is historical. We should probably change it, but
should change the configure build at the same time.
