33adcfb4d2 rename TAI -> MAI, being careful not to make MAILJMP instructions :)

b808588a3a Change MCSectionELF to represent a section semantically instead of
syntactically as a string, very similiar to what Chris did with MachO.
The parsing support and validation is not introduced yet.

38cff389af sink uniquing of sections out of MCContext into the ELF and PECOFF TLOF implementations.
MCContext no longer maintains a string -> section map.

ff4bc460c5 Make the big switch: Change MCSectionMachO to represent a section *semantically*
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?

93b6db3de9 sink the 'name' and 'isdirective' state out of MCSection into its derived classes.
This totally optimizes PIC16 sections by not having an 'isdirective' bit anymore!! ;-)

892e182393 1. Make MCSection an abstract class.
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.

MCSection instances.

968ff11967 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.

ed47a0409b split MCSection stuff out to its own .cpp file, add a new
MCSectionWithKind subclass of MCSection.
