preprocessing record. Use that link with clang_getCursorReferenced()
and clang_getCursorDefinition() to match instantiations of a macro to
the definition of the macro.

the macro definitions and macro instantiations that are found
during preprocessing. Preprocessing records are *not* generated by
default; rather, we provide a PPCallbacks subclass that hooks into the
existing callback mechanism to record this activity.
The only client of preprocessing records is CIndex, which keeps track
of macro definitions and instantations so that they can be exposed via
cursors. At present, only token annotation uses these facilities, and
only for macro instantiations; both will change in the near
future. However, with this change, token annotation properly annotates
macro instantiations that do not produce any tokens and instantiations
of macros that are later undef'd, improving our consistency.
Preprocessing directives that are not macro definitions are still
handled by clang_annotateTokens() via re-lexing, so that we don't have
to track every preprocessing directive in the preprocessing record.
Performance impact of preprocessing records is still TBD, although it
is limited to CIndex and therefore out of the path of the main compiler.

intrinsics. The intrinsic lookup code assumes that this check has been done
and assumes the names are at least 6 characters long. Valgrind complained
about this. pr6638.

BumpPtrAllocator-allocated region to allow it to be stored in a more
compact form and to avoid the need for a non-trivial destructor call.
Use this new mechanism in ScalarEvolution instead of
FastFoldingSetNode to avoid leaking memory in the case where a
FoldingSetNodeID uses heap storage, and to reduce overall memory
usage.

Apparently this happens under certain versions of glibc, so valgrind provides
the --run-libc-freeres=no option to avoid calling freeres(). This may increase
the number of "still reachable" blocks valgrind reports, but we don't care
about those, while this error breaks the buildbots.
There are upstream bugs about this at
http://sourceware.org/bugzilla/show_bug.cgi?id=10610 and
http://bugs.kde.org/show_bug.cgi?id=167483, but they don't look likely to be
fixed.

This affects functions with very complicated live intervals for physical

on this arrangement. This is similar to what's described in A2.5.2 ITSTATE.
