[ADT] Switch a bunch of places in LLVM that were doing single-character
...
splits to actually use the single character split routine which does
less work, and in a debug build is *substantially* faster.

Implement unique sections with an unique ID.
...
This allows the compiler/assembly programmer to switch back to a
section. This in turn fixes the bootstrap failure on powerpc (tested
on gcc110) without changing the ppc codegen at all.
I will try to cleanup the various getELFSection overloads in a followup patch.
Just using a default argument now would lead to ambiguities.

Close unique sections when switching away from them.
...
It is not possible to switch back to unique secitons, so close them
automatically when switching away.

Create symbols marking the start of a section earlier.
...
This lets us pass the symbol to the constructor and avoid the mutable field.
This also opens the way for outputting the symbol only when needed, instead
of outputting them at the start of the file.

MC: Remove superfluous section attribute flag definitions
...
Summary:
llvm/MC/MCSectionMachO.h and llvm/Support/MachO.h both had the same
definitions for the section flags. Instead, grab the definitions out of
support.
No functionality change.
