Change `SourceManager::getOrCreateContentCache` to take a `FileEntryRef`
and update call sites (mostly internal to SourceManager.cpp). In a
couple of cases this temporarily relies on `FileEntry::getLastRef`, but
those can be cleaned up once other APIs switch over.
The one change outside of SourceManager.cpp is in ASTReader.cpp, which
stops relying on the auto-degrade-to-`FileEntry*` behaviour from
`InputFile::getFile` since it now needs a `FileEntryRef`.

Change `SourceManager::createFileID(const FileEntry*)` to defer to
`SourceManager::createFileID(FileEntryRef)`. This fixes an unexercised
bug where the latter gained support for named pipes and the former
didn't, but since we're trying to remove all calls to the former it
doesn't really make sense to test this explicitly now that the
implementation is hollowed out.
This is a belated follow-up to 245218bb35,
which sunk named pipe support into FileManager and SourceManager. The
original version of that patch was based on top of
https://reviews.llvm.org/D92984, which removed the `FileEntry` overload
of `createFileID()`, and I missed the subtle difference when it was
rebased.
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.

The class `SymbolOccurrences` can store either a single `SourceRange`
in-place or multiple `SourceRanges` on the heap. In the latter case
the number of source ranges is stored in the internal representation
of the beginning `SourceLocation` of the in-place `SourceRange`
object.
This change gets rid of such hack by placing `SourceRange` in a union
which holds either a valid `SourceRange` or an `unsigned int` (a number
of ranges).
The change also adds `static_assert`s that check that `SourceRange` and
`SourceLocation` are trivially destructible (this is required for the

Add support for stdin to SourceManager and FileManager. Adds

Eventually the other buffers in `ContentCache` will sink to here as well

it's happening early for stdin to get rid of
CompilerInstance::InitializeSourceManager's final call to
`SourceManager::overrideFileContents`.

Handle named pipes natively in SourceManager and FileManager, removing a
call to `SourceManager::overrideFileContents` in
`CompilerInstance::InitializeSourceManager` (removing a blocker for
sinking the content cache to FileManager (which will incidently sink
this new named pipe logic with it)).
SourceManager usually checks if the file entry's size matches the
eventually loaded buffer, but that's now skipped for named pipes since
the `stat` won't reflect the full size. Since we can't trust
`ContentsEntry->getSize()`, we also need shift the check for files that
are too large until after the buffer is loaded... and load the buffer
immediately in `createFileID` so that no client gets a bad value from
`ContentCache::getSize`. `FileManager::getBufferForFile` also needs to
treat these files as volatile when loading the buffer.
Native support in SourceManager / FileManager means that named pipes can
also be `#include`d, and clang/test/Misc/dev-fd-fs.c was expanded to
check for that.
This is a new version of 3b18a594c7, which
was reverted in b346322019 since it was

Many non-language extensions are defined but also unused. This patch
removes them with their tests as they do not require compiler support.
The cl_khr_select_fprounding_mode extension is also removed because it
has been deprecated since OpenCL 1.1 and Clang doesn't have any specific
support for it.
The cl_khr_context_abort extension is only referred to in "The OpenCL
Specification", version 1.2 and 2.0, in Table 4.3, but no specification
is provided in "The OpenCL Extension Specification" for these versions.
Because it is both unused in Clang and lacks specification, this
extension is removed.
The following extensions are platform extensions that bring new OpenCL
APIs but do not impact the kernel language nor require compiler support.
They are therefore removed.
- cl_khr_gl_sharing, introduced in OpenCL 1.0
- cl_khr_icd, introduced in OpenCL 1.2
- cl_khr_gl_event, introduced in OpenCL 1.1
Note: this extension adds a new API to create cl_event but it also
specifies that these can only be used by clEnqueueAcquireGLObjects.
Hence, they cannot be used on the device side and the extension does
not impact the kernel language.
- cl_khr_d3d10_sharing, introduced in OpenCL 1.1
- cl_khr_d3d11_sharing, introduced in OpenCL 1.2
- cl_khr_dx9_media_sharing, introduced in OpenCL 1.2

- cl_khr_initialize_memory, introduced in OpenCL 1.2
- cl_khr_gl_depth_images, introduced in OpenCL 1.2
Note: this extension is related to cl_khr_depth_images but only the
latter adds new features to the kernel language.

- cl_khr_egl_event, introduced in OpenCL 1.2

PartialDiagnostic misses some functions compared to DiagnosticBuilder.
This patch refactors DiagnosticBuilder and PartialDiagnostic, extracts
the common functionality so that the streaming << operators are
shared.

- The goal of this patch is improve option compatible with RISCV-V GCC,
-mcpu support on GCC side will sent patch in next few days.
- -mtune only affect the pipeline model and non-arch/extension related
target feature, e.g. instruction fusion; in td file it called
TuneFeatures, which is introduced by X86 back-end[1].
- -mtune accept all valid option for -mcpu and extra alias processor
option, e.g. `generic`, `rocket` and `sifive-7-series`, the purpose is
option compatible with RISCV-V GCC.
- Processor alias for -mtune will resolve according the current target arch,
rv32 or rv64, e.g. `rocket` will resolve to `rocket-rv32` or `rocket-rv64`.
- Interaction between -mcpu and -mtune:
* -mtune has higher priority than -mcpu for pipeline model and
TuneFeatures.

Update clang/lib/Basic to stop relying on a `MemoryBuffer*`, using the
`MemoryBufferRef` from `getBufferOrNone` or `getBufferOrFake` instead of
`getBuffer`.
Differential Revision: https://reviews.llvm.org/D89394
Remove `ContentCache::getBuffer`, which always returned a
dereferenceable `MemoryBuffer*` and had a `bool*Invalid` out parameter,
and replace it with:
- `ContentCache::getBufferOrNone`, which returns
`Optional<MemoryBufferRef>`. This is the new API that consumers should
use. Later it could be renamed to `getBuffer`, but intentionally using
a different name to root out any unexpected callers.
- `ContentCache::getBufferPointer`, which returns `MemoryBuffer*` with
"optional" semantics. This is `private` to avoid growing callers and
`SourceManager` has temporarily been made a `friend` to access it.
Later paches will update the transitive callers to not need a raw
pointer, and eventually this will be deleted.
No functionality change intended here.
