Add the new Args / entry-access API.

The long-term goal here is to get rid of the functions
GetArgumentAtIndex() and GetQuoteCharAtIndex(), instead
replacing them with operator based access and range-based for
enumeration. There are a lot of callsites, though, so the
changes will be done incrementally, starting with this one.

Don't allow direct access to StreamString's internal buffer.

This is a large API change that removes the two functions from
StreamString that return a std::string& and a const std::string&,
and instead provide one function which returns a StringRef.

Direct access to the underlying buffer violates the concept of
a "stream" which is intended to provide forward only access,
and makes porting to llvm::raw_ostream more difficult in the
future.

Convert some Args index-based iteration to range-style iteration.

This is better for a number of reasons. Mostly style, but also:

1) Signed-unsigned comparison warnings disappear since there is
no loop index.
2) Iterating with the range-for style gives you back an entry
that has more than just a const char*, so it's more efficient
and more useful.
3) Makes code safter since the type system enforces that it's
impossible to index out of bounds.

Convert option tables to ArrayRefs.

This change is very mechanical. All it does is change the
signature of `Options::GetDefinitions()` and `OptionGroup::
GetDefinitions()` to return an `ArrayRef<OptionDefinition>`
instead of a `const OptionDefinition *`. In the case of the
former, it deletes the sentinel entry from every table, and
in the case of the latter, it removes the `GetNumDefinitions()`
method from the interface. These are no longer necessary as
`ArrayRef` carries its own length.

In the former case, iteration was done by using a sentinel
entry, so there was no knowledge of length. Because of this
the individual option tables were allowed to be defined below
the corresponding class (after all, only a pointer was needed).
Now, however, the length must be known at compile time to
construct the `ArrayRef`, and as a result it is necessary to
move every option table before its corresponding class. This
results in this CL looking very big, but in terms of substance
there is not much here.

*** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

Tables of command options in LLDB benefit from hand-formatting to make it
easier to scan a set of options with a relatively large number of positional
arguments. This commit standardizes their formatting throughout LLDB and
applies surrounding directives to exempt them from being formatted by
clang-format.

These kinds of exemptions should be rare cases that benefit significantly
from alternative formatting. They also imply a long-term obligation to
maintain their format since the automated tools will not do so.

Decoupled Options from CommandInterpreter.

Options used to store a reference to the CommandInterpreter instance
in the base Options class. This made it impossible to parse options
independent of a CommandInterpreter.

This change removes the reference from the base class. Instead, it
modifies the options-parsing-related methods to take an
ExecutionContext pointer, which the options may inspect if they need
to do so.
