warp shuffles. This allow distributing reduction on a warp for GPU targets.
Also add an execution test for warp reduction.

This is a fix for https://github.com/llvm/llvm-project/issues/55827.
When register we are trying to re-color is split the original register (we tried to recover)
has no uses after the split. However in rollback actions we assign back physical register to it.
Later it causes different assertions. One of them is in attached test.
This CL fixes this by avoiding assigning physical register back to register which has no usage
or its live interval now is empty.

As Fortran 2018 C802 and C873, if bind name is specified, there can only
be only one entity. The check for common block is missed before. As
Fortran 2018 8.5.5 point 2, the bind name is one identifier, which is
unique. That is, one entity can not have multiple bind names. Also add

This patch switches the build compiler for AIX from ibm-clang to clang. ibm-clang++_r has `-pthread` by default, but clang for AIX doesn't, so `-pthread` had to be added to the test config. A bunch of tests now pass, so the `XFAIL` was removed. This patch also switch the build to use the visibility support available in clang-15 to control symbols exported by the shared library (AIX traditionally uses explicit export lists for this purpose).

If an integer PHI has an illegal type (according to the data layout) and
it is only used by `trunc` or `trunc(lshr)` operations, we split the PHI
into various instructions in its predecessors:
6d1543a167/llvm/lib/Transforms/InstCombine/InstCombinePHI.cpp (L1536-L1543)
So this can produce code like the following:
Before:
```
pred:
...
bb:
%p = phi i8 [ %somevalue, %pred ], ...
...
%tobool = trunc i8 %p to i1
use %tobool
...
```
In this code, `%p` has an illegal integer type, `i8`, and its only used
in a `trunc` instruction later. In this case this pass puts extraction
code in its predecessors:
After:
```
pred:
...
%t = and i8 %somevalue, 1
%extract = icmp ne i8 %t, 0
bb:
%p.new = phi i1 [ %extract, %pred ], ...
use %p.new instead of %tobool
```
But this doesn't work if `pred` is a `catchswitch` BB because it cannot
have any non-PHI instructions. This CL ensures we bail out in that case.

ISDs only ever contains a single ISD opcode. We can simplify the code under this assumption. The code being removed was added back in 2016 in 0f26b0aeb4 to support FMAXNAN/FMINNAN, but at some point since then the motivating case was rewritten not to use the ISDs mechanism. No reason to keep the false generality around now.
Slow definition generators may suspend lookups to temporarily release the
session lock, allowing unrelated lookups to proceed.
Using this functionality is discouraged: it is best to make definition
generation fast, rather than suspending the lookup. As a last resort where
this is not possible, suspension may be used.
An API to wrap ExecutionSession::lookup, this allows C API clients to use async
lookup.
The immediate motivation for adding this is to simplify upcoming
definition-generator unit tests.
As we're adding more tests that need to convert between C and C++ flag values
this commit adds helper functions to support this. This patch also updates the
CAPIDefinitionGenerator to use these new utilities.

Per 7.11.1p1 - All [ieee_arithmetic and ieee_exceptions] functions are

these functions are elemental (and not impure), which implies pure.
Several of the remaining non-elemental functions are missing pure prefixes;
add them.
The code for scanning BOZ input allows for blanks and tabs to appear,
but can hang if they do and the BOZ input value is not followed by
extra valid digits; the repositioning for the second sweep simply
