This flag is set by most other tools and avoids extra stat() calls. The
frontend will diagnose anyway as it performs the check atomically while opening
files at point of use.
We could probably make Driver::CheckInputsExist default to false and only
enable it in the main 'clang' binary, or even better only perform the checks if
we know the tool is external but that needs more thought.

Update the strategy in r212083 to try JIT first and otherwise fall back to the
interpreter. This gives the best of both worlds and still builds fine with no
targets enabled.
Requires supporting changes from LLVM r212086.

Fixes the build when no targets are selected, or no native target is built.
This also better matches up with the description/title of the example and
demonstrates how clang can be used to run C++ on constrained environments
without file IO or executable memory permissions (e.g. iOS apps).
A comment is added explaining how to extend the demo with JIT support as
needed.

All callers were passing in "a.out" or garbage so a sensible default works fine
here as a cleanup.
This also brings about the possibility of adapting the value based on the
driver's compatibility mode in future.
The setting can still be changed via Driver::DefaultImageName as needed.

This moves the code to Job.cpp, which seems like a more natural fit,
and replaces the "is this a JobList? is this a Command?" logic with
a virtual function call.
It also removes the code duplication between PrintJob and
PrintDiagnosticJob and simplifies the code a little.
There's no functionality change here, except that the Executable is
now always printed within quotes, whereas it would previously not be
quoted in crash reports, which I think was a bug.

Also, it was the only reason that `argc` and `argv` were being passed
into createDiagnostics, so remove those parameters and clean up callers.

The class name is long enough without the llvm:: added.
Also bring in RefCountedBase and RefCountedBaseVPTR.

This removes the final dependency edge from any lib outside of CodeGen
to core. As a result we can, and do, trim the dependency on core
from libclang, PrintFunctionNames, the unit tests and c-index-test.
While at it, review and trim other unneeded dependencies.

Currently, all AST consumers are located in the Frontend library,
meaning that in a shared library configuration, Frontend has a
dependency on Rewrite, Checker and CodeGen. This is suboptimal for
clients which only wish to make use of the frontend. CodeGen in
particular introduces a large number of unwanted dependencies.
This patch breaks the dependency by moving all AST consumers with
dependencies on Rewrite, Checker and/or CodeGen to their respective
libraries. The patch therefore introduces dependencies in the other
direction (i.e. from Rewrite, Checker and CodeGen to Frontend).
After applying this patch, Clang builds correctly using CMake and
shared libraries ("cmake -DBUILD_SHARED_LIBS=ON").
N.B. This patch includes file renames which are indicated in the
patch body.
Changes in this revision of the patch:
- Fixed some copy-paste mistakes in the header files
- Modified certain aspects of the coding to comply with the LLVM
Coding Standards
