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.

16-bit long.

Also, we should be using BLX to call external function stubs.

 - Operands which are just a label should be parsed as immediates, not memory
   operands (from the assembler perspective).

 - Match a few more flavors of immediates.

 - Distinguish match functions for memory operands which don't take a segment
   register.

 - We match the .s for "hello world" now!

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.

don't modify the LLVM IR CFG, they may modify the MachineFunction CFG,

obviously be improved, but this is the minimal fix and restores us to the
previous behavior.
