any named parameters, e.g., this is accepted in C:
void f(...) __attribute__((overloadable));
although this would be rejected:
void f(...);
To do this, moved the checking of the "ellipsis without any named
arguments" condition from the parser into Sema (where it belongs anyway).

FunctionDecls.
Don't allow "overloadable" functions (in C) to be declared without a
prototype.

the various PPTokens that are pasted together to make it. In the course
of working on this, I discovered ParseObjCStringLiteral which needs some
work. I'll tackle it next.

When comparing if one Range is "less" than another, compare the actual APSInt
numeric values instead of their pointer addresses. This ensures that the
ImmutableSet in RangeSet always has a consistent ordering between Ranges. This
is critical for generating the same digest/hash for the contents of the sets.
This was a serious performance bug because it would often cause state caching
to be disabled along complicated paths.
Along the way:
- Put Range and RangeSet in the "anonymous namespace" and mark them hidden

back to the summary used when evaluating the statement associated with a
simulation node. This is now being used to help improve the checker's
diagnostics. To get things started, the checker now emits a path diagnostic
indicating that 'autorelease' is a no-op in GC mode.
Some of these changes are exposing further grossness in the interface between
BugReporter and the ExplodedGraph::Trim facilities. These really need to be
cleaned up one day.

are multiple IV's in a loop, some of them may under go signed
or unsigned wrapping even if the IV that's used in the loop
exit condition doesn't. Restrict sign-extension-elimination
and zero-extension-elimination to only those that operate on
the original loop-controlling IV.

- This idiom ensures that the result will have the right width and
type.
- Tested on most of x86_64/llvm-test to satisfy my paranoia.
- This fixes at least the following bugs:
o UnaryTypeTraitExpr wasn't setting the width correctly.
o Arithmetic on _Bool wasn't setting the width correctly.
And probably a number more.

- Makes an APSInt given a uint64_t and a type, with the appropriate
width and signedness to match the type. Yay for functional over
imperative.

keep searching for C++ headers when in C++ mode). In theory clang
should be able to find all of its own headers now. If not, the
CPATH or C_INCLUDE_PATH environment variables can be specified to
add a include path.
