Daniel Dunbar 63ec093b6e MC/X86/AsmMatcher: Use the new instruction cleanup routine to implement a
temporary workaround for matching inc/dec on x86_64 to the correct instruction.
 - This hack will eventually be replaced with a robust mechanism for handling
   matching instructions based on the available target features.

Bob Wilson 3c7cde466e Fix pr6543: svn r88806 changed MachineJumpTableInfo::getJumpTableIndex() to
always create a new jump table.  The intention was to avoid merging jump
tables in SelectionDAGBuilder, and to wait for the branch folding pass to
merge tables.  Unfortunately, the same getJumpTableIndex() method is also
used to merge tables in branch folding, so as a result of this change
branch tables are never merged.  Worse, the branch folding code is expecting
getJumpTableIndex to always return the index of an existing table, but with
this change, it never does so.  In at least some cases, e.g., pr6543, this
creates references to non-existent tables.

I've fixed the problem by adding a new createJumpTableIndex function, which
will always create a new table, and I've changed getJumpTableIndex to only
look at existing tables.

Dan Gohman 48d09cab66 Fix a bug found by inspection; in the __GNUC__ code, the alignment

Douglas Gregor 065f8d11ca Introduce the notion of a "preprocessing record", which keeps track of
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.

Dan Gohman 6556c8962c Add the ability to "intern" FoldingSetNodeID data into a
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.

Jeffrey Yasskin fa22878d9d Avoid a problem in libc_freeres() seen on a linux-i686 buildbot when running
under valgrind:

==19577== Invalid free() / delete / delete[]
==19577==    at 0x4C9C866: free (vg_replace_malloc.c:325)
==19577==    by 0x5121104: ??? (in /lib/libc-2.10.2.so)
==19577==    by 0x4C97412: _vgnU_freeres (vg_preloaded.c:62)
==19577==    by 0x5041486: __run_exit_handlers (exit.c:93)
==19577==    by 0x50414FE: exit (exit.c:100)
==19577==    by 0x5028B5C: (below main) (libc-start.c:254)
==19577==  Address 0xffffffff is not stack'd, malloc'd or (recently) free'd
==19577== 

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.
