5eaa54e210 make mcasmstreamer handle expanding 8 byte integer constants to 
4-byte constants if .quad isn't supported.  Switch a bunch of
methods used by the dwarf writer to use OutStreamer.EmitIntValue.

8eeba35bab revert 93934, removing the MCAsmInfo endianness bit. I can't 
stomache MCAsmInfo having this, and I found a better solution to
this layering issue.

c7b8814bb4 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.

significant regression on the # bytes generated by .fill.

aac138e84d Cleanup handling of .zerofill on darwin: 
1. TargetLoweringObjectFileMachO should decide if something
   goes in zerofill instead of having every target do it.
2. TargetLoweringObjectFileMachO should assign said symbols to
   the right MCSection, the asmprinters should just emit to the
   right section.
3. Since all zerofill stuff goes through mcstreamer anymore,
   MAI can have a bool "haszerofill" instead of having the textual
   directive to emit.

acd03ae679 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.

8c6ed05157 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();
