58d26c105b - Add getLSDAEncoding to the PowerPC backend. 
- Greatly improve the comments to the getLSDAEncoding method.

5678a9711b - Add a comment to the callback indicating that it's *extremely* not a good 
idea, but unfortunately necessary.
- Default to using 4-bytes for the LSDA pointer encoding to agree with the
  encoded value in the CIE.

d7bd67fa61 Change CurrentFnSym to be a non-const pointer since asmprinter mutates it 
as it emits code.  Switch .globl directives to use OutStreamer instead of
doing it textually (in x86)

6f360c3c91 now that MCSymbol::print doesn't use it's MAI argument, we can 
remove it and change all the code that prints MCSymbols to use 
<< instead, which is much simpler and cleaner.

f7c6508544 Get MCSymbol out of the mangling business, and move all the logic 
to Mangler.  Now MCSymbol just decides whether to slap quotes around
a symbol when printing it.

This also fixes some weirdness where two MCSymbols could be created
for the same symbol, if one needed to be mangled and got mangled to
the other one.

having to pass various fields from it in.  Simplify.

d78fcdd332 Retrying r91337: 
The CIE says that the LSDA point in the FDE section is an "sdata4". That's fine,
but we need it to actually be 4-bytes in the FDE for some platforms. Allow
individual platforms to decide for themselves.

b1b91d11db supplement CurrentFnName with CurrentFnSym, which will eventually

use mangler anymore.  CellSPU needs more invasive surgery.

7a3b1c5ffc DEBUG_VALUE is now variable sized, as it has a

d8faccbeab Add some debug routines to SelectionDAG to dump full DAGs. 
print/dumpWithDepth allows one to dump a DAG up to N levels deep.
dump/printWithFullDepth prints the whole DAG, subject to a depth limit
on 100 in the default case (to prevent infinite recursion).

Have CannotYetSelect to a dumpWithFullDepth so it is clearer exactly
what the non-matching DAG looks like.

c1b5223e76 Improve llvm.dbg.declare intrinsic by referring directly to the storage in its first argument, via function-local metadata (instead of via a bitcast). 
This patch also cleans up code that expects there to be a bitcast in the first argument and testcases that call llvm.dbg.declare.
It also strips old llvm.dbg.declare intrinsics that did not pass metadata as the first argument.

b6c8d75f62 Hook up llc's -filetype=obj to use MCStreamer if an MCCodeEmitter is available.

writer with the AsmPrinter MCInst/MCSection logic is forthcoming.
