There's probably never a good reason to iterate over unique_ptrs. This
lets us use range-for and say Job.foo instead of (*it)->foo in a few
places.

Diving into the memory leaks fixed by r213851 there was one case of a
memory leak of a CompilationDatabase due to not properly taking
ownership of the result of "CompilationDatabase::autoDetectFromSource".
Given that both implementations and callers have been using unique_ptr
to own CompilationDatabase objects - make this explicit in the API to
reduce the risk of further leaks.

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.

It moves them at the end of the range instead, so an extra erase is needed.

It is strange that this code works without the erase. On the other hand, removing the remove_if will make fail some tests.

FixedCompilationDatabase (FCD) requires that the arguments it consumes after
'--' must not include positional parameters or the argv[0] of the tool. This
patch relaxes those restrictions.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

This will allow us to delete the JSON parser from llvm.

The biggest change is a general change of strategy - instead
of storing StringRef's to the values for the command line and
directory in the input buffer, we store ScalarNode*'s. The
reason is that the YAML parser's getRawValue on ScalarNodes
returns a string that includes the quotes in case of double
quoted strings.

For the same reason we're removing the JSON parsing part of
the command line parsing - this means an extra copy for a
command line when it is requested (and only when it is requested).

Provides an API to run clang tools (FrontendActions) as standalone tools,
or repeatedly in-memory in a process. This is useful for unit-testing,
map-reduce style applications, source transformation daemons or command line
tools.

The ability to run over multiple translation units with different command
line arguments enables building up refactoring tools that need to apply
transformations across translation unit boundaries.

See tools/clang-check/ClangCheck.cpp for an example.
