<rdar://problem/13094134> Don't try to wire up typedef names for invalid anonymous tag declarations encountered during template instantiation.

Sema: Preserve attributes on parameters in instantiated function templates.

This was causing correctness issues for ARC and the static analyzer when a
function template has "consumed" Objective-C object parameters (i.e.
parameters that will be released by the function before returning).

The fix is threefold:
(1) Actually copy over the attributes from old ParmVarDecls to new ones.
(2) Have Sema::BuildFunctionType only work for building FunctionProtoTypes,
    which it was doing anyway. This allows us to pass an ExtProtoInfo
    instead of a plain ExtInfo and several flags.
(3) Drop param attributes as part of StripImplicitInstantiation, which is
    used when an implicit instantiation is followed by an explicit one.

Move clang tests that depend on llvm/ADT/Statistic.h to a subdir.

The subdirectory has a lit.local.cfg that marks the tests unsupported
if llvm was built without Asserts.  There will be a patch in LLVM
that disables statistics gathering when built without Asserts so
that full Release builds can be faster.  Statistics can also
be enabled by building with -DLLVM_ENABLE_STATS.

<rdar://problem/13170740> Be a little more careful when instantiating 'this' expressions.

[libclang] Change clang_findReferencesInFile and clang_findIncludesInFile to return an enum,
as suggested by Jordan.
