instead of syntactically as a string.  This means that it keeps track of the 
segment, section, flags, etc directly and asmprints them in the right format.
This also includes parsing and validation support for llvm-mc and 
"attribute(section)", so we should now start getting errors about invalid 
section attributes from the compiler instead of the assembler on darwin.

Still todo: 
1) Uniquing of darwin mcsections
2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h]
3) there are a few FIXMEs, for example what is the syntax to get the
   S_GB_ZEROFILL segment type?

'no_hash' modifier. Hopefully this will make Daniel happy :)

2. Move section switch printing to MCSection virtual method which takes a
   TAI.  This eliminates textual formatting stuff from TLOF.
3. Eliminate SwitchToSectionDirective, getSectionFlagsAsString, and 
   TLOFELF::AtIsCommentChar.

give the impls an object-file-specific name.  In the future
they can take different arguments etc.

so I generalized the class for VTRN in the .td file to handle all 3 of them.

directly from the intrinsics produced by the frontend.  If it is more
convenient to have a custom DAG node for using these to implement shuffles,
we can add that later.
