Change SectionKind to be a property that is true of a *section*, it
should have no state that is specific to particular globals in the
section.  In this case, it means the removal of the "isWeak" and
"ExplicitSection" bits.  MCSection uses the new form of SectionKind.

To handle isWeak, I introduced a new SectionInfo class, which is
SectionKind + isWeak, and it is used by the part of the code generator
that does classification of a specific global.

The ExplicitSection disappears.  It is moved onto MCSection as a new
"IsDirective" bit.  Since the Name of a section is either a section
or directive, it makes sense to keep this bit in MCSection.  Ultimately
the creator of MCSection should canonicalize (e.g.) .text to whatever
the actual section is.

Allow target intrinsics that return multiple values, i.e., struct types,
in SelectionDAGLowering::visitTargetIntrinsic.

This removes a bit of special-case code for vector types.  After staring
at it for a while, I managed to convince myself that it is not necessary.
The only case where TLI.getValueType() differs from MVT::getMVT is for iPTR,
so this code could potentially make a difference for a vector of pointers.
But, it looks like that is not supported.  Calling TLI.getValueType() on
a vector of pointers leads to the following sequence of calls:

TargetLowering::getValueType
MVT::getMVT
MVT::getVectorVT(iPTR, num elements)
MVT::getExtendedVectorVT
MVT::getTypeForMVT for iPTR
assertion fails "Type is not extended!"

So, unless I'm really missing something, this bit of code is irrelevant to
the current version of LLVM, which is consistent with the fact that I don't
see this code in other similar places.

add some comments on how this is *supposed* to work.  We don't
need the PreferredEHDataFormat hook, but I have yet-more refactoring to
do before I can zap it.

rearrange a conditional.  Even if this weren't #if 0'd out, this would
have no functionality change.

Simplify operand padding by keying off tabs in the asm stream.  If
padding is disabled, tabs get replaced by spaces except in the case of
the first operand, where the tab is output to line up the operands after
the mnemonics.

Add some better comments and eliminate redundant code.

Fix some testcases to not assume tabs.

llvm-mc: Support quoted identifiers.

PreferredEHDataFormat is always call with data and global, but this whole
thing is #if0'd out anyway.  Just simplify the code by reducing the interface.
Not deleting this is essential for Bill's continuing happiness.

move emitUsedDirectiveFor to TargetLoweringObjectFile and rename it to
indicate that it is a predicate, not an emitter.  This eliminates TAI
dependencies on Mangler and GlobalValue.

remove the PPCLinuxTargetAsmInfo implementation of PreferredEHDataFormat,
because it just calls the default impl.

Remove the PPCDarwinTargetAsmInfo version of PreferredEHDataFormat because
it just returns DW_EH_PE_absptr unless on 10.6.  However, 10.6 doesn't support
PPC, so the default impl is just fine.

Move a few more APIs back to 2.5 forms.  The only remaining ones left to change back are
metadata related, which I'm waiting on to avoid conflicting with Devang.
