Duncan P. N. Exon Smith 4652459f64 MC: Simplify MCSymbolData initialization and remove MCSymbol pointer 
Finally remove the `MCSymbolData::Symbol` pointer.  It was still being
used to track whether `MCSymbolData` had been initialized, but this is
better tracked by the bitfield in `MCSymbol`.

The only caller of `MCSymbolData::initialize()` was `MCAssembler`, which
(other than `Symbol`) passed in all-0 values.  Replace all that
indirection with a default constructor.

The main point is a cleanup (and there's more cleanup to do), but there
are also some small memory savings.  I measured ~989 MB down to ~975 MB,
cutting a little over 1% off the top of `llc`.

(I'm looking at `llc` memory usage on `verify-uselistorder.lto.opt.bc`;
see r236629 for details.)

Low Level Virtual Machine (LLVM)
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you're writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
