Summary:
https://reviews.llvm.org/rL321877 introduced the `OptTable::findNearest`
method, to find the closest edit distance option for a given string.
However, the implementation contained a bug: for a typo `-foo` with an
edit distance of 1 away from a valid option `--foo`, `findNearest`
would suggest a nearby option of `foo`. That is, the result would not
include the `--` prefix, and so was not a valid option.
Fix the bug by ensuring that the prefix string is initialized to one of
the valid prefixes for the option.

Summary:
Add a method `OptTable::findNearest`, which allows users of OptTable to
check user input for misspelled options. In addition, have llvm-mt
check for misspelled options. For example, if a user invokes
`llvm-mt /oyt:foo`, the error message will indicate that while an
option named `/oyt:` does not exist, `/out:` does.
The method ports the functionality of the `LookupNearestOption` method
from LLVM CommandLine to libLLVMOption. This allows tools like Clang
and Swift, which do not use CommandLine, to use this functionality to
suggest similarly spelled options.
As room for future improvement, the new method as-is cannot yet properly suggest
nearby "joined" options -- that is, for an option string "-FozBar", where
"-Foo" is the correct option name and "Bar" is the value being passed along
with the misspelled option, this method will calculate an edit distance of 4,
by deleting "Bar" and changing "z" to "o". It should instead calculate an edit
distance of just 1, by changing "z" to "o" and recognizing "Bar" as a
value. This commit includes a disabled test that expresses this limitation.

Summary:
This is a patch for clang autocomplete feature.
It will collect values which -analyzer-checker takes, which is defined in
clang/StaticAnalyzer/Checkers/Checkers.inc, dynamically.
First, from ValuesCode class in Options.td, TableGen will generate C++
code in Options.inc. Options.inc will be included in DriverOptions.cpp, and
calls OptTable's addValues function. addValues function will add second
argument to Option's Values class. Values contains string like "foo,bar,.."
which is handed to Values class
in OptTable.

Summary:
`clang --autocomplete=-std` will show
```
-std: Language standard to compile for
-std= Language standard to compile for
-stdlib= C++ standard library to use
```
after this change.
However, showing HelpText with completion in bash seems super tricky, so
this feature will be used in other shells (fish, zsh...).

By default, we display only options that are not

Summary:
We don't want to autocomplete flags whose Flags class has `NoDriverOption` when argv[1] is not `-cc1`.
Another idea for this implementation is to make --autocomplete a cc1
option and handle it in clang Frontend, by porting --autocomplete
handler from Driver to Frontend, so that we can handle Driver options
and CC1 options in unified manner.

Remove std::move() around xvalue so that copy elision is eligible.
In case that copy elision is not appliable, the c++ standard also
guarantees the move semantics on xvalue. Thus, it is not necessary
to wrap Args with std::move.
This also silence a warning since r240345.

The one caller that does anything other than keep this variable on the
stack is the single use of DerivedArgList in Clang, which is a bit more
interesting but can probably be cleaned up/simplified a bit further
(have DerivedArgList take ownership of the InputArgList rather than
needing to reference its Args indirectly) which I'll try to after this.

This patch contains the LLVM side of the fix of PR17239.
This bug that happens because the /link (clang-cl.exe argument) is
marked as "consume all remaining arguments". However, when inside a
response file, /link should only consume all remaining arguments inside
the response file where it is located, not the entire command line after
expansion.
My patch will change the semantics of the RemainingArgsClass kind to
always consume only until the end of the response file when the option
originally came from a response file. There are only two options in this
class: dash dash (--) and /link.

Link.exe's command line options are case-insensitive. This patch
adds a new attribute to OptTable to let the option parser to compare
options, ignoring case.
Command lines are generally case-insensitive on Windows. CL.exe is an
exception. So this new attribute should be useful for other commands
running on Windows.

Clients of the option parsing library should handle it explicitly

This adds KIND_REMAINING_ARGS, a class of options that consume
all remaining arguments on the command line.
This will be used to support /link in clang-cl, which is used
to forward all remaining arguments to the linker.
It also allows us to remove the hard-coded handling of "--",
allowing clients (clang and lld) to implement that functionality
themselves with this new option class.

Everything that comes after -- should be treated as a filename. This
enables passing in filenames that would otherwise be conflated with
command-line options.
This is especially important for clang-cl which supports options
starting with /, which are easily conflatable with Unix-style
path names.

Summary:
This allows the clang driver to put MSVC compatible options in the same
enumerator space as its normal options but exclude them from normal
option parsing.
Also changes the standard ParseArgs() method to consider unknown
arguments with a leading slash as being inputs rather than flags.
