When trying to run test-release.sh on Solaris 11.4 for 9.0.0 rc4, I failed initially
because Solaris lacks chrpath. This patch accounts for that and allowed the run to
continue.
Tested on amd64-pc-solaris2.11 and sparcv9-sun-solaris2.11.

These tests were temporarily missing when the big Makefile
simplification patch landed, so this just applies the same change

Folding for fma/fmuladd was added here:
rL202914
...and as seen in existing/unchanged tests, that works to propagate NaN
if it's already an input, but we should fold an fma() that creates NaN too.
From IEEE-754-2008 7.2 "Invalid Operation", there are 2 clauses that apply
to fma, so I added tests for those patterns:
c) fusedMultiplyAdd: fusedMultiplyAdd(0, ∞, c) or fusedMultiplyAdd(∞, 0, c)
unless c is a quiet NaN; if c is a quiet NaN then it is implementation
defined whether the invalid operation exception is signaled
d) addition or subtraction or fusedMultiplyAdd: magnitude subtraction of
infinities, such as: addition(+∞, −∞)

After reverting the deletion of the functionalities/breakpoint tests,
we now have some tests twice in the test/ folder which breaks dotest:
* commands/breakpoint/basic
* functionalities/breakpoint/breakpoint_command
After looking over these tests, I think it makes sense to only
keep the original functionalities/ folder. The commands/breakpoint/basic
test are not exclusively testing the breakpoint command itself, so
they shouldn't be in commands/ in the first place. Note that these
folders have identical contents (beside small adjustments regarding
the Makefile which landed after the restructuring).

Summary:
They can be confusing -- what does it mean to call a setter without a
value? Also, some setters, like `setPrintTemplateTree` had `false` as
the default value!
The callers are largely not using these default arguments anyway.

Up to now, we've decided whether to sink address calculations using GEPs or

this change simply overcomes this for when using C# settings in the .clang-format file

Summary:
I don't have a direct motivational case for this,
but it would be good to have this for completeness/symmetry.
This pattern is basically the motivational pattern from
https://bugs.llvm.org/show_bug.cgi?id=43251
but with different predicate that requires that the offset is non-zero.
The completeness bit comes from the fact that a similar pattern (offset != zero)
will be needed for https://bugs.llvm.org/show_bug.cgi?id=43259,
so it'd seem to be good to not overlook very similar patterns..
Proofs: https://rise4fun.com/Alive/21b
Also, there is something odd with `isKnownNonZero()`, if the non-zero
knowledge was specified as an assumption, it didn't pick it up (PR43267)

Summary:
This adds `-fwasm-exceptions` (in similar fashion with
`-fdwarf-exceptions` or `-fsjlj-exceptions`) that turns on everything
with wasm exception handling from the frontend to the backend.
We currently have `-mexception-handling` in clang frontend, but this is
only about the architecture capability and does not turn on other
necessary options such as the exception model in the backend. (This can
be turned on with `llc -exception-model=wasm`, but llc is not invoked
separately as a command line tool, so this option has to be transferred
from clang.)
Turning on `-fwasm-exceptions` in clang also turns on
`-mexception-handling` if not specified, and will error out if
`-mno-exception-handling` is specified.

This patch gets rid of the Invalid state of

This modifies the tool somewhat to only create files when about to run
the "interestingness" test, and delete them immediately after - this
means some more files will be created sometimes (when "double checking"
work - which should probably be fixed/avoided anyway).
This now creates temporary files, rather than only unique ones, and also
uses ToolOutputFile (without ever calling "keep") to ensure the files
are deleted as soon as the interestingness test is run.

AVX512 instructions can cause a frequency drop on these CPUs. This
can negate the performance gains from using wider vectors. Enabling
prefer-vector-width=256 will prevent generation of zmm registers
unless explicit 512 bit operations are used in the original source
code.
I believe gcc and icc both do something similar to this by default.

First we were asserting that the ValNo of a VA was the wrong value. It doesn't actually
make a difference for us in CallLowering but fix that anyway to silence the assert.
The bigger issue was that after fixing the assert we were generating invalid MIR
because the merging/unmerging of values split across multiple registers wasn't
also implemented for memory locs. This happens when we run out of registers and
have to pass the split types like i128 -> i64 x 2 on the stack. This is do-able, but
for now just fall back.

Before, we only checked the callee for swifterror. However, we should also be
checking the caller to see if it has a swifterror parameter.
Since we don't currently handle outgoing arguments, this didn't show up in the
swifterror.ll testcase.
Also, remove the swifterror checks from call-translator-tail-call.ll, since
they are covered by the existing swifterror testing. Better to have it all in
one place.

Originally the idea was for providers to be defined close to where they
are used. While this helped designing the providers in such a way that
they don't depend on each other, it also means that it's not possible to
access them from a central place. This proved to be a problem for some
providers and resulted in them living in the reproducer class.
The ProcessGDBRemote provider is the last remaining exception. This
patch makes things consistent and moves it into the reproducer like the
other providers.
