identical field in the Type ODS class. Add support for generating
documentation for attribute constraints defined using this field. This

getExtAttrForI32Param() is the method to be used for determining the type of
extension attribute (if any) that is to be added for a signed/unsigned
argument.
Previously, the SExt attribute was always added to the i32 ldexp* argument as
it was expected to be ignored by targets not needing it. This patch now
changes this so that it is only added for the targets that need it in the
first place.
Putchar() argument is now also extended as required by the target (SystemZ in
the test), to fix the issue below. Many more libcalls will be handled
similarly in a following patch.

Any header or module file in the Flang source directory is of no use to
the compiler unless it is copied into the build directory. Indeed, all
compiler search paths are relative to the compiler executable (flang-new
in our case). Hence, "omp_lib.h" should be copied into the build
directory alongside other compiler-provided files that can be "included"
(header files) or "used" (module files).
For now, "omp_lib.h" is copied into "<build-dir>/include/flang/OpenMP".
We may decide to change this in future. For example, Clang copies a
bunch of runtime headers into “<build-dir>/lib/clang/<version-number>”.
We could also consider using a similar header from a different
sub-project.
Flang's driver search path is updated accordingly. A rule for
"installing" the "omp_lib.h" header is _yet to be added_ (we will also
need to determine the suitable location for this).

This adds cc1 options for enabling and disabling opaque pointers
on the clang side. This is not super useful now (because
-mllvm -opaque-pointers and -Xclang -opaque-pointers have the same
visible effect) but will be important once opaque pointers are
enabled by default in clang. In that case, it will only be
possible to disable them using the cc1 -no-opaque-pointers option.

Since the threads/frame view is taking only a small part on the right side
of the screen, only a part of the function name of each frame is visible.
It seems rather wasteful to spell out 'frame' there when it's obvious
that it is a frame, it's better to use the space for more of the function
name.

The `move` instruction has one of the most complicate sets of variants, so
we're refactoring it first before finishing up rest of the data
instructions in a separate patch.
Note that since we're introducing more `move` variants, the codegen
actually got improved in terms of code size.
Check for supported target architecture instead of the host arch when
deciding to execute non-runtime tests.

This change introduces two new methods: `finalizeSegment` and `appendIndex`; and removes three old methods: `endDim`, `appendCurrentPointer`, `appendIndex`. The two new methods better encapsulate their algorithms, thus allowing to remove repetitious code in several other places.

Without the fix ivars with anonymous types can trigger errors like
> error: 'TestClass::structIvar' from module 'Target' is not present in definition of 'TestClass' provided earlier
> [...]
> note: declaration of 'structIvar' does not match
It happens because types of ivars from different modules are considered
to be different. And it is caused by not merging anonymous `TagDecl`
from different modules.
To fix that I've changed `serialization::needsAnonymousDeclarationNumber`
to handle anonymous `TagDecl` inside `ObjCInterfaceDecl`. But that's not
sufficient as C code inside `ObjCInterfaceDecl` doesn't use interface
decl as a decl context but switches to its parent (TranslationUnit in
most cases). I'm changing that to make `ObjCContainerDecl` the lexical
decl context but keeping the semantic decl context intact.
Test "check-dup-decls-inside-objc.m" doesn't reflect a change in
functionality but captures the existing behavior to prevent regressions.

Add support for computing the symbolic integer lexmin of a polyhedron.
This finds, for every assignment to the symbols, the lexicographically
minimum value attained by the dimensions. For example, the symbolic lexmin
of the set
`(x, y)[a, b, c] : (a <= x, b <= x, x <= c)`
can be written as
```
x = a if b <= a, a <= c
x = b if a < b, b <= c
```
This also finds the set of assignments to the symbols that make the lexmin unbounded.

D120018 altered this combine to work on buildvectors as opposed to
shuffle dup's. This works well for dups and other things that are
expanded into buildvectors. Some shuffles are legal though, and stay as
vector_shuffle through lowering. This expands the transform to also
handle shuffles, so that we can turn mul(shuffle(sext into
mul(sext(shuffle and more readily make smull/umull instructions. This
can come up from the SLP vectorizer adding shuffles that are costed from
extends.

All uses of JSONGenerator in debugserver would create a JSON text
dump of the object collection, then copy that string into a
binary-escaped string, then send it up to the lldb side or
make a compressed version and send that.
This adds a DumpBinaryEscaped method to JSONGenerator which
does the gdb remote serial protocol binary escaping directly,
and removes the need to pass over the string and have an
additional copy in memory.

This commit restructures how TypeID is implemented to ideally avoid
the current problems related to shared libraries. This is done by changing
the "implicit" fallback path to use the name of the type, instead of using
a static template variable (which breaks shared libraries). The major downside to this
is that it adds some additional initialization costs for the implicit path. Given the
use of type names for uniqueness in the fallback, we also no longer allow types
defined in anonymous namespaces to have an implicit TypeID. To simplify defining
an ID for these classes, a new `MLIR_DEFINE_EXPLICIT_INTERNAL_INLINE_TYPE_ID` macro
was added to allow for explicitly defining a TypeID directly on an internal class.
To help identify when types are using the fallback, `-debug-only=typeid` can be
used to log which types are using implicit ids.
This change generally only requires changes to the test passes, which are all defined
in anonymous namespaces, and thus can't use the fallback any longer.

After this patch, all the remaining FileEntry::getName calls are subtle

This ELF note is aarch64 and Android-specific. It specifies to the
dynamic loader that specific work should be scheduled to enable MTE
protection of stack and heap regions.
Current synthesis of the ".note.android.memtag" ELF note is done in the
Android build system. We'd like to move that to the compiler. This patch
adds the --memtag-stack, --memtag-heap, and --memtag-mode={async, sync,
none} flags to the linker, which synthesises the note for us.
Future changes will add -fsanitize=memtag* flags to clang which will
pass these through to lld.
