Chris Lattner 324c86600d eliminate the magic AbsoluteDebugSectionOffsets MAI hook,
which is really a property of the section being referenced.
Add a predicate to MCSection to replace it.

Yay for reduction in magic.

Chris Lattner ff234e09b9 Eliminate SetDirective, and replace it with HasSetDirective.
Default HasSetDirective to true, since most targets have it.

The targets that claim to not have it probably do, or it is
spelled differently. These include Blackfin, Mips, Alpha, and
PIC16.  All of these except pic16 are normal ELF targets, so
they almost certainly have it.

Chris Lattner ecb457c4e2 linux/ppc does use alignment in bytes, not pow-2. This fixes PR6129.
It looks like linux/arm and linux/mips have the same setting, which 
are probably wrong.  Someone who cares about ARM and MIPS should 
investigate with the testcase in PR6129.

Chris Lattner 2b4364fe03 revert 93934, removing the MCAsmInfo endianness bit. I can't
stomache MCAsmInfo having this, and I found a better solution to
this layering issue.

Chris Lattner 003b5c8472 give MCAsmInfo a 'has little endian' bit. This is unfortunate, but
I really want clients of the streamer to be able to say "emit this
64-bit integer" and have it get broken down right by the streamer.

I may change this in the future, we'll see how it works out.

Chris Lattner b866602f06 Big change #1 for personality function references:
Eliminate the PersonalityPrefix/Suffix & NeedsIndirectEncoding
fields from MAI: they aren't part of the asm syntax, they are
related to the structure of the object file.

To replace their functionality, add a new 
TLOF::getSymbolForDwarfGlobalReference method which asks targets
to decide how to reference a global from EH in a pc-relative way.

The default implementation just returns the symbol.  The default
darwin implementation references the symbol through an indirect
$non_lazy_ptr stub.  The bizarro x86-64 darwin specialization
handles the weird "foo@GOTPCREL+4" hack.

DwarfException.cpp now uses this to emit the reference to the
symbol in the right way, and this also eliminates another 
horrible hack from DwarfException.cpp:

-    if (strcmp(MAI->getPersonalitySuffix(), "+4@GOTPCREL"))
-      O << "-" << MAI->getPCSymbol();

Chris Lattner 4e465598f0 eliminate the PPC backend's implementation of EmitExternalGlobal
and use PersonalityPrefix/Suffix to achieve the same effect (like
the x86 backend).

This changes the code generated for ppc static mode, but guess what,
we were generating this before:

	.byte	0x9B                                        ; Personality (indirect pcrel sdata4)
	.long	___gxx_personality_v0-.                     ; Personality

which is not correct! (it is not an 'indirect' reference).
