File override structures now contain per-source overrides for headers.
For now, modified headers are written to disk when the Migrator is done.
This is only temporary behaviour since we can expect headers to be
changed by migrating multiple source files. The changes need to be
merged after all migrations are complete.

A more flexible container for storing overrides is required for headers. Before
a source goes through the transform pipeline, any headers it references will be
in their original state and unaffected by transforms applied to other sources.
Therefore overrides for headers need to be kept separate for each source file.
This patch doesn't introduce support for storing header overrides yet. It only
replaces the existing structure and makes any necessary changes to support it.

Execute's Data parameter is now optional, so we won't allocate memory
for it on Windows and we'll close the process handle.
The Unix code should probably do something similar to avoid accumulation
of zombie children that haven't been waited on.
Tested on Linux and Windows.

When choosing a default CPU, clang used to pick ARM7TDMI (which has Thumb) even
when the more restrictive armv4 triple was specified. This should fix that.

implicit definition of a copy operation is deprecated. Add a warning for this
to -Wdeprecated. This warning is disabled by default for now, pending
investigation into how common this situation is.

- 'register' storage class
- dynamic exception specifications
Only the former check is enabled by default for now (the latter might be quite noisy).

Architecture specific code should reside in architecture specific directory
not in Atom. Looks like there are no efforts being made at this moment to
support ARM, so let's remove it for now.

Introduce CXXStdInitializerListExpr node, representing the implicit
construction of a std::initializer_list<T> object from its underlying array.
The AST representation of such an expression goes from an InitListExpr with a
flag set, to a CXXStdInitializerListExpr containing a MaterializeTemporaryExpr
containing an InitListExpr (possibly wrapped in a CXXBindTemporaryExpr).
This more detailed representation has several advantages, the most important of
which is that the new MaterializeTemporaryExpr allows us to directly model
lifetime extension of the underlying temporary array. Using that, this patch
*drastically* simplifies the IR generation of this construct, provides IR
generation support for nested global initializer_list objects, fixes several
bugs where the destructors for the underlying array would accidentally not get
invoked, and provides constant expression evaluation support for
std::initializer_list objects.

operator<< so that functions are printed as just their name instead of as their
entire definition, which is excessively verbose in this context.

CXXCtorInitializers to the point where we perform the questionable lifetime
extension. This exposed a selection of false negatives in the warning.

properly. This warning checks that the #ifndef and #define directives at
the beginning of a header refer to the same macro name. Includes a fix-it
hint to correct the header guard.

It was only used to implement ExecuteAndWait and ExecuteNoWait. Expose just
those two functions and make Execute and Wait implementations details.
