99831068c8 Add 129518 back with a fix for when we are producing eh just because of debug info. 
Change ELF systems to use CFI for producing the EH tables. This reduces the
size of the clang binary in Debug builds from 690MB to 679MB.

198c39a4fe Add an instcombine for constructs like a | -(b != c); a select is more 
canonical, and generally leads to better code.  Found while looking at

268d8f22f8 Fix an infinite alternation in JumpThreading where two transforms would repeatedly undo each other. The solution is to perform more aggressive constant folding to make one of the edges just folded away rather than trying to thread it. 
Fixes <rdar://problem/9284786>.

e89c19ab7b In the pre-RA scheduler, maintain cmp+br proximity. 
This is done by pushing physical register definitions close to their
use, which happens to handle flag definitions if they're not glued to
the branch. This seems to be generally a good thing though, so I
didn't need to add a target hook yet.

The primary motivation is to generate code closer to what people
expect and rule out missed opportunity from enabling macro-op
fusion. As a side benefit, we get several 2-5% gains on x86
benchmarks. There is one regression:
SingleSource/Benchmarks/Shootout/lists slows down be -10%. But this is
an independent scheduler bug that will be tracked separately.
See rdar://problem/9283108.

Incidentally, pre-RA scheduling is only half the solution. Fixing the
later passes is tracked by:
<rdar://problem/8932804> [pre-RA-sched] on x86, attempt to schedule CMP/TEST adjacent with condition jump

Fixes:
<rdar://problem/9262453> Scheduler unnecessary break of cmp/jump fusion

85a4af977a Documented bugpoint --compile-custom --compile-command. 
I've used it a few times to reduce unit tests and gotten one request for information on it. It's not easy to use correctly because bugpoint doesn't tell you when you're doing it wrong.

88e2acc24c rework FoldBranchToCommonDest to exit earlier when there is a bonus 
instruction around, reducing work.

Greatly simplify handling of debug instructions.  There is no need to
build up a vector of them and then move them into the one predecessor
if we're processing a block.  Instead just rescan the block and *copy*
them into the pred.  If a block gets merged into multiple preds, this
will retain more debug info.

0b9c16295a As Dan pointed out, movzbl, movsbl, and friends are nicer than their alias 
(movzx/movsx) because they give more information. Revert that part of the patch.

4b667cd995 Vectors with different number of elements of the same element type can have 
the same allocation size but different primitive sizes(e.g., <3xi32> and
<4xi32>).  When ScalarRepl promotes them, it can't use a bit cast but
should use a shuffle vector instead.

920274b4dd Passing unroll parameters (unroll-count, threshold, and partial unroll) via LoopUnroll class's ctor. Doing so 
will allow multiple context with different loop unroll parameters to run.  This is a minor change and no effect 
on existing application.

Relocations between the object modules are properly resolved, as in the
following trivial example:

$ cat t.c
int foo();
int main() {
    return foo();
}
$ cat foo.c
int foo() {
    return 65;
}
$ clang -c t.c -fno-asynchronous-unwind-tables
$ clang -c foo.c -fno-asynchronous-unwind-tables
$ llvm-rtdyld t.o foo.o ; echo $?
loaded '_main' at: 0x10015c000
