[OpenMP][Offload][AMDGPU] Fix offload tests failure after the new triple (#208617)
Offload tests failed after introducing the new triple. This PR attempts
to address that. It includes the changes in
https://github.com/llvm/llvm-project/pull/208551. In addition, it also
made following changes:
- Updated flang builder that our buildbot uses;
- Updated the CMakeLists for offload and AMDGPU device runtime (a little
duplications to avoid breaking other buildbots);
- Added per target linker path and mapping for lit substitution/features
in lit config;
- Updated hard-coded check lines in the tests.
This PR reduces the failed offload tests from 246 to 2 on my test runs
locally. Test results and the two failed tests:
```

[Clang] Treat address-of template substitution as SFINAE
Taking the address of a function template specialization can instantiate
its trailing return type as part of a SFINAE probe:
struct X {};
template <class T> void f(T) = delete;
template <class T> auto probe(T t) -> decltype(f(t), void());
template <class T, class = decltype(&probe<T>)> int test(int);
template <class T> char test(...);
static_assert(sizeof(test<X>(0)) == sizeof(char));
Here, substituting the return type of probe<X> selects the deleted f<X>.
The deleted call is in the immediate context of substitution, so it should
remove test(int) from overload resolution. GCC accepts this example. Clang
instead kept deduction as successful and later replayed the stored
diagnostic as a hard error.
The call-deduction path already checks the SFINAE trap after finishing
template argument deduction. Do the same for the address-of path, so the
stored diagnostic is not replayed after deduction succeeds.
lang/clisp: Use Berkeley db 18
clisp was using the default bdb, version 5, which is deprecated and
can be considered insecure. Upgrade to 18.

[flang][OpenACC] Preserve source extents in section strides (#208594)
Use the source array extent when advancing cumulative strides across
scalar subscripts, whose selected extent is one. Add coverage for mixed
scalar and triplet dimensions.
[libc++] Merge atomic-wait contention tables into a single table (#208493)
PR #161086 (73a13839d3ec) introduced a new contention table for atomics
with a native size. However, this also increases the size of the dylib
and the footprint of processes using the dylib by a non-negligible
margin.
To mitigate this issue, this change folds the two tables into a single
one. The native waiter count can be stored for free inside padding that
was previously unused.

[libc++] Add MSVC's implementation of exception_ptr for Windows (#94977)
Microsoft is happy to contribute our implementation of exception_ptr for
Windows, under the Apache License v2.0 with LLVM Exception that our STLs
share.
* excptptr.cpp, copied verbatim as:
https://github.com/microsoft/STL/blob/e36ee6c2b9bc6f5b1f70776c18cf5d3a93a69798/stl/src/excptptr.cpp

The implementation was integrated into libc++:
* Deleted STL copy of <exception>. All standard exception classes are
already provided by libc++'s standard headers.
* Replaced MSVC STL naming conventions and macros (_STD,
_CRTIMP2_PURE, _Ref_count_base, _Ptr_base, _EXCEPTION_RECORD, etc.)
with standard libc++ style and identifiers (_LIBCPP_EXPORTED_FROM_ABI,
__double_leading_underscore variable/function names).
* Replaced internal MSVC CRT headers (<trnsctrl.h>,

ValueTracking: Generalize known frexp exponent range to any constant (#208316)
Extend computeKnownExponentRangeFromContext beyond the special case of a
dominating fabs(V) compare against exactly 1.0 to any finite limit.
Generalizing below 1.0 exposes a soundness issue: frexp(0) has exponent
0, so a bound derived assuming a nonzero value could wrongly exclude it
when the limit implies a negative maximum exponent. Query fcZero and
clamp the maximum exponent to at least 0 when the source may be zero.

[lldb] Improved formatting of 'register read' command. (#188049)
Made alignment of 'register read' command's output to be dynamic to the
register's name lengths -> `=` signs of different registers align when
printed as sets, also aligned when picked in some custom ordering. No
alignment between separate sets is included (i.e, each set is aligned to
itself only). Sample change:
```
Micro-architectural Registers:
r_pc = 0x0000108c main.xexe`main + 20 at main.c:5:5
instr_trace_r_init_print = 0x00
wb_csr_file_r_mstatus = 0x00000000
wb_csr_file_r_mie = 0x00000000

devel/tla+: new port
TLA+ is a language for modeling software above the code level and
hardware above the circuit level. The tool most commonly used by
engineers is the TLC model checker, but there is also a proof
checker. TLA+ is based on mathematics and does not resemble any
programming language. Most engineers will find PlusCal to be the
easiest way to start using TLA+.
The graphical TLA Toolbox IDE is not included. It is a separate
Eclipse RCP application that would be better as its own port.

[clang] more useful error message for decomposition declaration missing initializer (#127924)
#90107
Diagnostic message for decomposition declaration missing an initializer
only highlights the declared identifier. This change adds an additional
diagnostic message to highlight the token found where the initializer
was expected. So, for example:
auto [a, b] S = {1, 2}
The new error points to 'S' and says that 'S' was found where an
initializer was expected.
