This ports a number of OpenCL and fast-math flags for floating point
over to the new marshalling infrastructure.
As part of this, `Opt{In,Out}FFlag` were enhanced to allow other flags to
imply them, via `DefaultAnyOf<>`. For example:
```
defm signed_zeros : OptOutFFlag<"signed-zeros", ...,
"LangOpts->NoSignedZero",
DefaultAnyOf<[cl_no_signed_zeros, menable_unsafe_fp_math]>>;
```
defines `-fsigned-zeros` (`false`) and `-fno-signed-zeros` (`true`)
linked to the keypath `LangOpts->NoSignedZero`, defaulting to `false`,
but set to `true` implicitly if one of `-cl-no-signed-zeros` or
`-menable-unsafe-fp-math` is on.
Note that the initial patch was written Daniel Grumberg.

In clang <3.9 the `unique_ptr` constructor that is supposed to allow
for Derived to Base conversion does not work. Remove this if we drop
support for such configurations.
This is the same fix as in fda901a987ddd, and it updates the comments
to better reflect the actual issue. The same thing reproduces with
libc++ with older clangs.
This is a workaround for a bug in older versions of Clang when. The
constructor that is supposed to allow for Derived to Base conversion
does not work. Remove this if we drop support for such configurations.
This change includes the following:
- Add additional information in the relevant table-gen files to encode
the necessary information to automatically parse the argument into a
CompilerInvocation instance and to generate the appropriate command
line argument from a CompilerInvocation instance.
- Extend OptParserEmitter to emit the necessary macro tables as well as
constant tables to support parsing and generating command line
arguments for options that provide the necessary information.
- Port some options to use this new system for parsing and generating
command line arguments.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
For lldb and dsymutil, the command guide is essentially a copy of its
help output generated by libOption. Making sure the two stay in sync is
tedious and error prone. Given that we already generate the help from a
tablegen file, we might as well generate the RST as well.
This adds a tablegen backend for generating Sphinx/RST command guides
from the tablegen file.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
Add support for autocompleting values of -std= by including
LangStandards.def. This patch relies on D36782, and is using two-stage
code generation.

This reverts commit 7c46b80c022e18d43c1fdafb117b0c409c5a6d1e.
r311552 broke lld buildbot because I've changed OptionInfos type from
ArrayRef to vector. However the bug is fixed, so I'll commit this again.

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.

This is patch for GSoC project, bash-completion for clang.
To use this on bash, please run `source clang/utils/bash-autocomplete.sh`.
bash-autocomplete.sh is code for bash-completion.
In this patch, Options.td was mainly changed in order to add value class
in Options.inc.

Internally both these methods just return the result of getValue on either a StringInit or a CodeInit object. In both cases this returns a StringRef pointing to a string allocated in the BumpPtrAllocator so its not going anywhere. So we can just pass that StringRef along.
This is a fairly naive patch that targets just the build failures caused by this change. There's additional work that can be done to avoid creating std::string at call sites that still think getValueAsString returns a std::string. I'll try to clean those up in future patches.

This makes using array_pod_sort significantly safer. The implementation relies
on function pointer casting but that should be safe as we're dealing with void*
here.

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.

This makes option aliases more powerful by enabling them to
pass along arguments to the option they're aliasing.
For example, if we have a joined option "-foo=", we can now
specify a flag option "-bar" to be an alias of that, with the
argument "baz".
This is especially useful for the cl.exe compatible clang driver,
where many options are aliases. For example, this patch enables
us to alias "/Ox" to "-O3" (-O is a joined option), and "/WX" to
"-Werror" (again, -W is a joined option).

Manage Inits in a FoldingSet. This provides several benefits:
- Memory for Inits is properly managed
- Duplicate Inits are folded into Flyweights, saving memory
- It enforces const-correctness, protecting against certain classes
of bugs
The above benefits allow Inits to be used in more contexts, which in
turn provides more dynamism to TableGen. This enhanced capability
will be used by the AVX code generator to a fold common patterns
together.
