This improves DYLD_PRINT_STATISTICS from:
total time: 6.0 milliseconds (100.0%)
total images loaded:  5 (4 from dyld shared cache, 3 needed no fixups)
total segments mapped: 0, into 0 pages with 0 pages pre-fetched
total images loading time: 0.0 milliseconds (1.4%)
total rebase fixups:  0
total rebase fixups time: 0.0 milliseconds (0.0%)
total binding fixups: 7,928
total binding symbol lookups: 4,087, average images searched per symbol: 1.9
total binding fixups time: 4.7 milliseconds (79.2%)
total bindings lazily fixed up: 170 of 4,372
total init time time: 1.1 milliseconds (19.2%)
total images with weak exports:  2

to:
total time: 1.4 milliseconds (100.0%)
total images loaded:  5 (4 from dyld shared cache, 4 needed no fixups)
total segments mapped: 0, into 0 pages with 0 pages pre-fetched
total images loading time: 0.0 milliseconds (5.7%)

This reduces the time to -fsyntax-only cocoa.h with PTH from 0.192s to 0.184 (4.3%)

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.

2. va_arg of types passed in two SSE registers didn't account for
extra space in register save area.

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.

Add assert to isICE that, on success, result must be the same as
EvaluateAsInt()... this enforces a minimum level of sanity.

 - 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.

llvm-svn: 64864

 - 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.

specialization of class templates, e.g.,

  template<typename T> class X;

  template<> class X<int> { /* blah */ };

Each specialization is a different *Decl node (naturally), and can
have different members. We keep track of forward declarations and
definitions as for other class/struct/union types.

This is only the basic framework: we still have to deal with checking
the template headers properly, improving recovery when there are
failures, handling nested name specifiers, etc.
