[mlir][Affine] Add support for multi-store producer fusion
This patch adds support for producer-consumer fusion scenarios with
multiple producer stores to the AffineLoopFusion pass. The patch
introduces some changes to the producer-consumer algorithm, including:
* For a given consumer loop, producer-consumer fusion iterates over its
producer candidates until a fixed point is reached.
* Producer candidates are gathered beforehand for each iteration of the
consumer loop and visited in reverse program order (not strictly guaranteed)
to maximize the number of loops fused per iteration.
In general, these changes were needed to simplify the multi-store producer
support and remove some of the workarounds that were introduced in the past
to support more fusion cases under the single-store producer limitation.
This patch also preserves the existing functionality of AffineLoopFusion with
one minor change in behavior. Producer-consumer fusion didn't fuse scenarios
with escaping memrefs and multiple outgoing edges (from a single store).
Multi-store producer scenarios will usually (always?) have multiple outgoing
edges so we couldn't fuse any with escaping memrefs, which would greatly limit
the applicability of this new feature. Therefore, the patch enables fusion for
these scenarios. Please, see modified tests for specific details.

[OpenCL] Refactor of targets OpenCL option settings
Currently, there is some refactoring needed in existing interface of OpenCL option
settings to support OpenCL C 3.0. The problem is that OpenCL extensions and features
are not only determined by the target platform but also by the OpenCL version.
Also, there are core extensions/features which are supported unconditionally in
specific OpenCL C version. In fact, these rules are not being followed for all targets.
For example, there are some targets (as nvptx and r600) which don't support
OpenCL C 2.0 core features (nvptx.languageOptsOpenCL.cl, r600.languageOptsOpenCL.cl).
After the change there will be explicit differentiation between optional core and core
OpenCL features which allows giving diagnostics if target doesn't support any of
necessary core features for specific OpenCL version.
This patch also eliminates `OpenCLOptions` instance duplication from `TargetOptions`.
`OpenCLOptions` instance should take place in `Sema` as it's going to be modified
during parsing. Removing this duplication will also allow to generally simplify
`OpenCLOptions` class for parsing purposes.

[mlir][Linalg] Add a padding option to Linalg tiling
This revision allows the base Linalg tiling pattern to optionally require padding to
a constant bounding shape.
When requested, a simple analysis is performed, similar to buffer promotion.
A temporary `linalg.simple_pad` op is added to model padding for the purpose of
connecting the dots. This will be replaced by a more fleshed out `linalg.pad_tensor`
op when it is available.
In the meantime, this temporary op serves the purpose of exhibiting the necessary
properties required from a more fleshed out pad op, to compose with transformations
properly.

[clang][cli] NFC: Pass CC1Option explicitly to BoolOption
When `Bool{F,G}Option` were introduced, they were designed after the existing `Opt{In,Out}FFlag` in that they implied `CC1Option` for the `ChangedBy` flag.
This means less typing, but can be misleading in situations when the `ResetBy` has explicit `CC1Option` and `ChangedBy` doesn't.

[clang][cli] NFC: Move prefix to the front of BoolOption
The prefix used to be the last (optional) argument to BoolOption. This decision was made with the expectation that only few command line options would need to pass it explicitly instead of using Bool{F,G}Option. It turns out that a considerable number of options don't conform to Bool{F,G}Option and need to provide the prefix anyways. This sometimes requires to explicitly pass `BothFlags<[]>`.
This patch makes prefix the first parameter, so it now directly precedes the spelling base string. Now 8 options dropped `BothFlags<[]>` and only two options (`pthread` and `emit_llvm_uselists`) need to pass an empty prefix.

* Fixes FuncOp visibility to properly use None instead of the empty string and defaults it to None.
* Implements what was documented for requiring that trailing __init__ args `loc` and `ip` are keyword only.
* Adds a check to `InsertionPoint.insert` so that if attempting to insert past the terminator, an exception is raised telling you what to do instead. Previously, this would crash downstream (i.e. when trying to print the resultant module).
* Renames `_ods_build_default` -> `build_generic` and documents it.
* Removes `result` from the list of prohibited words and for single-result ops, defaults to naming the result `result`, thereby matching expectations and what is already implemented on the base class.

Suppress non-conforming GNU paste extension in all standard-conforming modes
The GNU token paste extension that removes the comma in , ## __VA_ARGS__
conflicts with C99/C++11's requirements when a variadic macro has no
named parameters: according to the standard, an invocation as FOO()
gives it a single empty argument, and concatenation of anything with an
empty argument is well-defined. For this reason, the GNU extension was
already disabled in C99 standard-conforming mode. It was not yet
disabled in C++11 standard-conforming mode.
The associated comment suggested that GCC keeps this extension enabled
in C90/C++03 standard-conforming mode, but it actually does not, so
rather than adding a check for C++ language version, this change simply
removes the check for C language version.
