fixed incorrect lowering of ISD::SUB node. SUB has only one result value.

It wasn't caught during tests because we never got a sub generated, (i8 was always getting promoted to int, which in turn was broken into subc/sube). Though the optimizer leaves an i8 sub now.

Change Thumb2 jumptable codegen to one that uses two level jumps:
...
Before:
adr r12, #LJTI3_0_0
ldr pc, [r12, +r0, lsl #2 ]
LJTI3_0_0:
.long LBB3_24
.long LBB3_30
.long LBB3_31
.long LBB3_32
After:
adr r12, #LJTI3_0_0
add pc, r12, +r0, lsl #2
LJTI3_0_0:
b.w LBB3_24
b.w LBB3_30
b.w LBB3_31
b.w LBB3_32
This has several advantages.
1. This will make it easier to optimize this to a TBB / TBH instruction +
(smaller) table.
2. This eliminate the need for ugly asm printer hack to force the address
into thumb addresses (bit 0 is one).
3. Same codegen for pic and non-pic.
4. This eliminate the need to align the table so constantpool island pass
won't have to over-estimate the size.
Based on my calculation, the later is probably slightly faster as well since
ldr pc with shifter address is very slow. That is, it should be a win as long
as the HW implementation can do a reasonable job of branch predict the second
branch.

More migration to raw_ostream, the water has dried up around the iostream hole.

- Some clients which used DOUT have moved to DEBUG. We are deprecating the

downside of leaving code in -Asserts builds, and of hiding potentially
unnecessary computations.

Revert r75581: it causes massive breakage in the Ada
...
testsuite, due to exception handling not working
correctly. Maybe because the libgcc unwinder is
miscompiled - not sure, and I won't have time to
look into it before leaving on holiday. Note that
miscompilations of libgcc are not picked up by the
nightly testers, because they dynamically link with
libgcc, so pick up the system version rather than
the version built as part of llvm-gcc. This is a
nasty flaw in the nightly testers. (On the other
hand the Ada testsuite links with the just built
libgcc).

Let each target determines whether a machine instruction is dead. If true, that allows late codeine passes to delete it.

This is considered a workaround. The problem is some targets are not modeling side effects correctly. PPC is apparently one of those. This patch allows ppc llvm-gcc to bootstrap on Darwin. Once we find out which instruction definitions are wrong, we can remove the PPCInstrInfo workaround.

Pass in the unfortunately named "LessPrivatePrefix" for the

"LinkerPrivatePrefix". It seems to have been used in only one place before I
started this "linker_private" business. I'm thinking that a rename is in
order...

Add plumbing for the `linker_private' linkage type. This type is meant for

"private" symbols which the assember shouldn't strip, but which the linker may
remove after evaluation. This is mostly useful for Objective-C metadata.
This is plumbing, so we don't have a use of it yet. More to come, etc.

Switch Alpha over to the new call lowering style. New code mostly
...
copied from the SystemZ target. I don't think this causes any
significant changes to the output (I compared the assembly, and the
results appeared to be essentially unchanged), although I don't actually
have an Alpha to test on.
I would appreciate if anyone with the appropriate hardware could test
this. I'm not sure if that includes anyone subscribed to llvm-commits,
though.
