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.

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.
