Second set of ARM/MC/ELF changes.
...
Added ARM specific ELF section types.
Added AttributesSection to ARMElfTargetObject
First step in unifying .cpu assembly tag with ELF/.o
llc now asserts on actual ELF emission on -filetype=obj :-)

Add hook in MCSection to decide when to use "optimized nops", for each
...
section kind. Previously, optimized nops were only used for MachO.
Also added tests for ELF and COFF.

Move logic of determining ELF entsize from the .s printer to initialization
...
time. That way, the EntrySize field is initialized for other code paths,
namely, the .ll -> .o code path.

ELF entry size support.
...
Some ELF sections contain fixed-sized entries. Provide a way to record
the entry size of a section.

MC: Add dyn_cast support to MCSection.
...
- Of questionable utility, since in general anything which wants to do this should probably be within a target specific hook, which can rely on the sections being of the appropriate type. However, it can be useful for short term hacks.

move elf section uniquing to MCContext. Along the way

merge XCore's section into MCSectionELF

eliminate the magic AbsoluteDebugSectionOffsets MAI hook,
...
which is really a property of the section being referenced.
Add a predicate to MCSection to replace it.
Yay for reduction in magic.

fix MCSectionELF to not leak memory, just like I did for MCSymbol.
...
MCSectionMachO is already fine (yay for fixed size arrays?),
MCSectionCOFF still leaks.

resolve a fixme: the "nonexecutable stack directive" is actually
...
a .section. Switch to it with SwitchSection.
However, I think that this directive should be safe on any ELF target.
If so, we should hoist it up out of the X86 and SystemZ targets.

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.
