Improve formatting of #defines.

Two improvements:
1) Always leave at least one space before "\". Otherwise is can look bad
   and there is a risk of unwillingly joining to characters to a different
   token.
2) Use the full column limit for single-line #defines.

First step towards adding a parent map to the ASTContext.

This does not yet implement the LimitNode approach discussed.

The impact of this is an O(n) in the number of nodes in the AST
reduction of complexity for certain kinds of matchers (as otherwise the
parent map gets recreated for every new MatchFinder).

See FIXMEs in the comments for the direction of future work.

ClangFormat.rst: Fix two small typos

Use the actual ABI-determined C calling convention for runtime
calls and declarations.

LLVM has a default CC determined by the target triple.  This is
not always the actual default CC for the ABI we've been asked to
target, and so we sometimes find ourselves annotating all user
functions with an explicit calling convention.  Since these
calling conventions usually agree for the simple set of argument
types passed to most runtime functions, using the LLVM-default CC
in principle has no effect.  However, the LLVM optimizer goes
into histrionics if it sees this kind of formal CC mismatch,
since it has no concept of CC compatibility.  Therefore, if this
module happens to define the "runtime" function, or got LTO'ed
with such a definition, we can miscompile;  so it's quite
important to get this right.

Defining runtime functions locally is quite common in embedded
applications.
