Sphinx has the `option` directive. Most option descriptions
in `clang/docs/UsersManual.rst` used it but some didn't.
This commit changes the remaining option descriptions to use
the `option` directive. This makes a consistent view in HTML.
The `option` directive automatically creates a cross-reference target.
So labeling by `.. _opt_XXX:` is almost unnecessary. However, options
with and without `no-` (e.g. `-fno-show-column`/`-fshow-column`)
cannot be distinguish for the cross-reference. So some required
`.. _opt_XXX:` directives are kept unremoved.

For generic targets such as SPIR-V clang sets all OpenCL
extensions/features as supported by default. However
concrete targets are unlikely to support all extensions
features, which creates a problem when such generic SPIR-V
binary is compiled for a specific target later on.
To allow compile time diagnostics for unsupported features
this flag is now being exposed in the clang driver.

As we are trying to reach parity between opencl-c.h and
-fdeclare-opencl-builtins, ensure the documentation mentions that new
builtins should be added to both.

There already exists cl_khr_fp64 extension. So OpenCL C 3.0
and higher should use the feature, earlier versions still
use the extension. OpenCL C 3.0 API spec states that extension
will be not described in the option string if corresponding
optional functionality is not supported (see 4.2. Querying Devices).
Due to that fact the usage of features for OpenCL C 3.0 must
be as follows:
```
$ clang -Xclang -cl-ext=+cl_khr_fp64,+__opencl_c_fp64 ...
$ clang -Xclang -cl-ext=-cl_khr_fp64,-__opencl_c_fp64 ...
```
e.g. the feature and the equivalent extension (if exists)
must be set to the same values

Add documentation that explains how to extend clang with the new
extensions/features. The guidelines also detail clang's position
about the extension pragmas for the new functionality.
