Original commit message:"
The current infrastructure in lib/Interpreter has a tool, clang-repl, very
similar to clang-interpreter which also allows incremental compilation.
This patch moves clang-interpreter as a test case and drops it as conditionally
built example as we already have clang-repl in place.

This patch also ignores ppc due to missing weak symbol for __gxx_personality_v0
which may be a feature request for the jit infrastructure. Also, adds a missing
build system dependency to the orc jit.

Additionally, this patch defines a custom exception type and thus avoids the
requirement to include header <exception>, making it easier to deploy across
systems without standard location of the c++ headers.

D105553 added NoStateChangeFuncVisitor, an abstract class to aid in creating
notes such as "Returning without writing to 'x'", or "Returning without changing
the ownership status of allocated memory". Its clients need to define, among
other things, what a change of state is.
For code like this:
f() {
g();
}
foo() {
f();
h();
}
We'd have a path in the ExplodedGraph that looks like this:
-- <g> -->
/ \
--- <f> --------> --- <h> --->
/ \ / \
-------- <foo> ------ <foo> -->
When we're interested in whether f neglected to change some property,
NoStateChangeFuncVisitor asks these questions:
÷×~
-- <g> -->
ß / \$ @&#*
--- <f> --------> --- <h> --->
/ \ / \
-------- <foo> ------ <foo> -->
Has anything changed in between # and *?
Has anything changed in between & and *?
Has anything changed in between @ and *?
...
Has anything changed in between $ and *?
Has anything changed in between × and ~?
Has anything changed in between ÷ and ~?
...
Has anything changed in between ß and *?
...
This is a rather thorough line of questioning, which is why in D105819, I was
only interested in whether state *right before* and *right after* a function
call changed, and early returned to the CallEnter location:
if (!CurrN->getLocationAs<CallEnter>())
return;
Except that I made a typo, and forgot to negate the condition. So, in this
patch, I'm fixing that, and under the same hood allow all clients to decide to
do this whole-function check instead of the thorough one.

Set up basic infrastructure for 64-bit ARM architecture support in JITLink. It allows for loading a minimal object file and resolving a single relocation. Advanced features like GOT and PLT handling or relaxations were intentionally left out for the moment.
This patch follows the idea to keep implementations for ARM (32-bit) and Aaarch64 (64-bit) separate, because:
* it might be easier to share code with the MachO "arm64" JITLink backend
* LLVM has individual targets for ARM and Aaarch64 as well

A small subset of the NEON instruction set is legal in streaming mode.
This patch adds support for the following vector to integer move
instructions:
0x00 1110 0000 0001 0010 11xx xxxx xxxx # SMOV W|Xd,Vn.B[0]
0x00 1110 0000 0010 0010 11xx xxxx xxxx # SMOV W|Xd,Vn.H[0]
0100 1110 0000 0100 0010 11xx xxxx xxxx # SMOV Xd,Vn.S[0]
0000 1110 0000 0001 0011 11xx xxxx xxxx # UMOV Wd,Vn.B[0]
0000 1110 0000 0010 0011 11xx xxxx xxxx # UMOV Wd,Vn.H[0]
0000 1110 0000 0100 0011 11xx xxxx xxxx # UMOV Wd,Vn.S[0]
0100 1110 0000 1000 0011 11xx xxxx xxxx # UMOV Xd,Vn.D[0]
Only the zero index variants are legal, all others indexes are illegal.
To support this, new instructions are defined specifically for zero
index which is hardcoded, along an implicit 'VectorIndex0' operand.
Since the index operand is implicit and takes no bits in the encoding,
custom decoding is required to add the operand.
I'm not sure if this is the best approach but the predicate constraint
on a subset of an operand is unusual. Would be interested to hear some
alternatives.
The instructions are predicated on 'HasNEONorStreamingSVE', i.e. they're
enabled by either +neon or +streaming-sve. This follows on from the work
in D106272 to support the subset of SVE(2) instructions that are legal
in streaming mode.
Depends on D107902.

DialectAsmParser::parseKeyword is rejecting `'i' digit+` while it is
a valid identifier according to mlir/docs/LangRef.md.
Integer types actually used to be TOK_KEYWORD a while back before the
change: 6af866c58d.
This patch Modifies `isCurrentTokenAKeyword` to return true for tokens that
match integer types too.
The motivation for this change is the parsing of `!fir.type<{` `component-name: component-type,`+ `}>`
type in FIR that represent Fortran derived types. The component-names are
parsed as keywords, and can very well be i32 or any ixxx (which are
valid Fortran derived type component names).
The Quant dialect type parser had to be modified since it relied on `iw` not
being parsed as keywords.

The size of common block should be extended to cover any storage
sequence that are storage associated with the common block via
equivalences (8.10.2.2 point 1 (2)).
In symbol size and offset computation, the size of the common block
was not always extended to cover storage association. It was only done
if the "base symbol of an equivalence group"(*) appeared in a common block
statement. Correct this to cover all cases where a symbol appearing in a
common block statement is storage associated.
(*) the base symbol of an equivalence group is the symbol whose storage
starts first in a storage association (if several symbols starts first,
the base symbol is the last one visited by the algorithm going through
the equivalence sets).

Summary: Now in libcxx and clang, all the coroutine components are
defined in std::experimental namespace.
And now the coroutine TS is merged into C++20. So in the working draft
like N4892, we could find the coroutine components is defined in std
namespace instead of std::experimental namespace.
And the coroutine support in clang seems to be relatively stable. So I
think it may be suitable to move the coroutine component into the
experiment namespace now.
But move the coroutine component into the std namespace may be an break
change. So I planned to split this change into two patch. One in clang
and other in libcxx.
This patch would make clang lookup coroutine_traits in std namespace
first. For the compatibility consideration, clang would lookup in
std::experimental namespace if it can't find definitions in std
namespace and emit a warning in this case. So the existing codes
wouldn't be break after update compiler.
