Chris Lattner 9f06f911d1 the latest assembler that runs on powerpc 10.4 machines doesn't 
support aligned comm.  Detect when compiling for 10.4 and don't
emit an alignment for comm.  THis will hopefully fix PR8198.

Chris Lattner aed00fa039 fix GetOrCreateTemporarySymbol to require a name, clients 
should use CreateTempSymbol() if they don't care about the
name.

Chris Lattner be3242b523 finally give Mangler a getSymbol method, which returns an MCSymbol 
for a global instead of messing around with string buffers.

Chris Lattner 47bef1a8a2 make TargetLoweringObjectFile::getExprForDwarfReference 
just make unnamed temp symbols instead of having to come
up with its own names.

Chris Lattner 03627cb12c fix a fixme in TargetLoweringObjectFile::getExprForDwarfReference 
where we used ot create an MCSymbol for ".".  Now emit an assembler
temporary label and reference it instead of "." textually.

Chris Lattner 2562356992 rename getSymbolForDwarf* to getExprForDwarf* since it returns 
an MCExpr and not an MCSymbol.  Change it to take an MCStreamer,
which is currently unused.

No functionality change.

Chris Lattner 71c30c164f move three lowering hooks from MAI to TLOF and make one of them 
semantic instead of syntactic.  This completes MCization of
darwin/x86[-64]!

Anton Korobeynikov ae4ccc10da Preliminary patch to improve dwarf EH generation - Hooks to return Personality / FDE / LSDA / TType encoding depending on target / options (e.g. code model / relocation model) - MCIzation of Dwarf EH printer to use encoding information - Stub generation for ELF target (needed for indirect references) - Some other small changes here and there

Chris Lattner cd2915e467 stop using the .lcomm pseudoop on darwin, instead, directly use the 
.zerofill directive.  Streamerize its generation.

Chris Lattner b253421711 make TLOF subclassify BSS based on linkage type into private, external 
and everything else (weak).

Chris Lattner a986aa33eb fix a significant difference between llvm and gcc on ELF systems: 
GCC would put weak zero initialized mutable data in the .bss section,
we would put it into a crasy '.gnu.linkonce.b.test,"aw",@nobits' 
section.  Fixing this will allow simplifications next up.

Chris Lattner 5b585f8b1a introduce a section kind for common linkage. Use this to slightly 
simplify and commonize some of the asmprinter logic for globals.

This also avoids printing the MCSection for .zerofill, which broke
the llvm-gcc build.

Chris Lattner 1d371882b6 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.

Chris Lattner 83e872e1c4 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.
