Since 8866793b4e ("[OpenCL] Add OpenCL builtin test generator",
2021-06-09) there are two emitters in this file, so move the
file-level comment to the appropriate class.
Add a new clang-tblgen flag `-gen-clang-opencl-builtin-tests` that
generates a .cl file containing calls to every builtin function
defined in the .td input.
This patch does not add any use of the new flag yet, so the only way
to obtain a generated test file is through a manual invocation of
clang-tblgen. A test making use of this emitter will be added in a
followup commit.

This reapplies commit 95033eb3 that reverted commit 1d9e8e13.
The tests were failing on Windows due to spaces and backslashes in paths not being handled carefully.
This patch adds support for inferred modules to the dependency scanner.
Effectively a cherry-pick of https://github.com/apple/llvm-project/pull/699 authored by @Bigcheese with libclang and other changes omitted.
Contains following changes:
1. [Clang][ScanDeps] Ignore __inferred_module.map dependency.
* This shows up with inferred modules, but it doesn't exist on disk, so don't report it as a dependency.
2. [Clang][ScanDeps] Use the module map a module was inferred from for inferred modules.
Also includes a smoke test that uses clang-scan-deps output to perform an explicit build. There's no intention to duplicate whatever `test/Modules` contains, just to verify the produced command-line does "work" (with very loose definition of work).
Split from D100934.

We have vector operations on double vector and float scalar. For
example, vfwadd.wf is such a instruction.
vfloat64m1_t vfwadd_wf(vfloat64m1_t op0, float op1, size_t op2);
We should specify F and D extensions for it.

This patch makes the builtin operand order match the C operand order
for all intrinsics. With this we can use clang_builtin_alias for
all overloaded intrinsics.
This should further reduce the test time for vector intrinsics.

We only apply `clang_builtin_alias` to non-masked builtins.
Masked builtins could not use `clang_builtin_alias` because the
operand order is different between overloaded intrinsics and builtins.
A bunch of test cases need to be updated.

Instead of using a MinVersion and MaxVersion field, encode the version
of a builtin using a mask that aligns better with version handling in
OpenCLOptions.h. In addition, this saves a field in the BuiltinTable.
This change allows a finer-grained control over the OpenCL versions in
which a builtin is available: instead of a range, we can now toggle
each version individually.
The fine-grained version control is not yet exposed on the TableGen
definitions side, as changes for OpenCL 3 feature optionality still
need to be defined and will affect how we want to expose these.

This fixes a subtle issue where:
svprf(pg, ptr, SV_ALL /*is sv_pattern instead of sv_prfop*/)
would be quietly accepted. With this change, the function declaration
guards that the third parameter is a `enum sv_prfop`. Previously `svprf`
would map directly to `__builtin_sve_svprfb`, which accepts the enum
operand as a signed integer and only checks that the incoming range is
valid, meaning that SV_ALL would be discarded as being outside the valid
immediate range, but would have allowed SV_VL1 without issuing a warning
(C) or error (C++).

The previous implementation was insufficient for checking statement
attribute mutual exclusion because attributed statements do not collect
their attributes one-at-a-time in the same way that declarations do. So
the design that was attempting to check for mutual exclusion as each
attribute was processed would not ever catch a mutual exclusion in a
statement. This was missed due to insufficient test coverage, which has
now been added for the [[likely]] and [[unlikely]] attributes.
The new approach is to check all of attributes that are to be applied
to the attributed statement in a group. This required generating
another DiagnoseMutualExclusions() function into AttrParsedAttrImpl.inc.
This patch changes the builtin prototype to use 'b' (boolean) instead
of the default integer element type. That fixes the dup/dupq intrinsics
when compiling with C++.
This patch also fixes one of the defines for __ARM_FEATURE_SVE2_BITPERM.

Just because an attribute is a statement attribute doesn't mean it's
not also a declaration attribute. In Clang, there are not currently any
DeclOrStmtAttr attributes that require mutual exclusion checking, but
downstream clients discovered this issue.
Currently, when one or more attributes are mutually exclusive, the
developer adding the attribute has to manually emit diagnostics. In
practice, this is highly error prone, especially for declaration
attributes, because such checking is not trivial. Redeclarations
require you to write a "merge" function to diagnose mutually exclusive
attributes and most attributes get this wrong.
This patch introduces a table-generated way to specify that a group of
two or more attributes are mutually exclusive:
def : MutualExclusions<[Attr1, Attr2, Attr3]>;
This works for both statement and declaration attributes (but not type
attributes) and the checking is done either from the common attribute
diagnostic checking code or from within mergeDeclAttribute() when
merging redeclarations.
RVV intrinsics has new overloading rule, please see
82aac7dad4
Changed:
1. Rename `generic` to `overloaded` because the new rule is not using C11 generic.
2. Change HasGeneric to HasNoMaskedOverloaded because all masked operations
support overloading api.
3. Add more overloaded tests due to overloading rule changed.

This requires changes to TableGen files and some C++ files due to
incompatible multiclass template arguments that slipped through
before the improved handling.
Clang currently automates a fair amount of diagnostic checking for
declaration attributes based on the declarations in Attr.td. It checks
for things like subject appertainment, number of arguments, language
options, etc. This patch uses the same machinery to perform diagnostic
checking on statement attributes.
Add new field PermuteOperands to mapping different operand order between
C/C++ API and clang builtin.
