1d04aa78f3 replace printBasicBlockLabel with EmitBasicBlockStart,
now that printBasicBlockLabel is only used for starting
a MBB.  This allows elimination of a bunch of arguments.

a602bebb61 devirtualize AsmPrinter::printBasicBlockLabel since it is never overridden.
Move GetMBBSymbol up to AsmPrinter and make printBasicBlockLabel use it so that
we only have one place that decides what to name bb labels.  Hopefully various
clients of printBasicBlockLabel can start using GetMBBSymbol instead.

4bd8040d14 Fix PR4948 (and a leak): by not destroying the DwarfException
object, the timer it creates was not being deleted.  Since the
timer belonged to a static timer group, the timer group would
be destroyed on shutdown, and would notice and complain that
not all timers it contained were destroyed.

9e5c2065c5 Revert part of my r81424 patch. I removed what looked like superfluous padding
from the exception tables. However, Duncan explained why it's a can of worms to
do it the GCC way. I went back to doing it the LLVM way and added Duncan's
explanation so that I don't do this again in the future.

243ac566e2 Don't hardcode the TType format size. In fact, rework the code so that it's more
like what GCC outputs. The mysterious code to insert padding wasn't in GCC at
all. I modified the TType base offset code to calculate the offset like GCC
does, though.

bf56268ff9 Remove the "#if 0" that Noone loved. It wasn't really necessary, because the
code within it was the same inside and out. There's still a problem of the
TypeInfoSize should be the size of the TType format encoding (at least that's
what GCC thinks it should be).

da3e7547fb Believe it or not, this is a simplification. :-)
Basically, this patch is working towards removing the hard-coded values that are
output for the CIE. In particular, the CIE augmentation and the CIE augmentation
size. Both of these should be calculated. In the process, I was able to make a
bunch of code simpler.

The encodings for the personality, LSDA, and FDE in the CIE are still not
correct. They should be generated either from target-specific callbacks (blech!)
or grokked from first-principles.

321bc99a74 remove DebugLoc from MCInst and eliminate "Comment printing" from
the MCInst path of the asmprinter.  Instead, pull comment printing
out of the autogenerated asmprinter into each target that uses the
autogenerated asmprinter.  This causes code duplication into each
target, but in a way that will be easier to clean up later when more
asmprinter stuff is commonized into the base AsmPrinter class.

This also fixes an xcore strangeness where it inserted two tabs
before every instruction.

e819cfbc71 change selectiondag to add the sign extended versions of immediate operands
to instructions instead of zero extended ones.  This makes the asmprinter
print signed values more consistently.  This apparently only really affects
the X86 backend.

51ae4a23da When emitting a label for a PostCall safe point, the machine
instruction to insert before can be end(). getDebugLoc on
end() returns an invalid value, therefore use the debug
loc of the call instruction, and give it to InsertLabel.

2512a42548 Fix a thinko: When lowering fneg with xor, bitcast the operands
from floating-point to integer first, and bitcast the result
back to floating-point. Previously, this test was passing by
falling back to SelectionDAG lowering. The resulting code isn't
as nice, but it's correct and CodeGen now stays on the fast path.
