These two tests were intended to cover the CU code paths, but invoked
llvm-mc using a generic "darwin" platform. However, MC only attempts to
emit CU for `macos >= 10.6` [1]. Thus we adjust the tests accordingly.

When known at compile time, Ew.d and Dw.d output edit descriptors
should respect limitations from the standard on the value of a
kP scale factor with respect to the digit count (d), at least for
values of k other than zero.
Under the hood this prints the same as `QualType::getAsString()` but cuts out the middle-man when that string is sent to another raw_ostream.
Also cleaned up all the call sites where this occurs.

This patch replaces getargspec with getfullargspec in funcutils.py.
getargspec has been deprecated by python 11x release. This is
important to run LLDB testsuite in Windows/Arm64 platform
where Python native will be available from python release onwards.
Note: getfullargspec is not available in python 2

Note that the underlying flush implementation does not yet fully implement
the POSIX standard. It is complete with respect to the C standard
however. A future change will add the POSIX behavior. It should not affect
the implementation of the fflush function however as the POSIX behavior
will be added in a lower layer.

This patch extends the scope of VPlan to also include the exit (aka
middle) block.
For now, the exit block remains empty, but handling of exit values will
subsequently be moved to VPlan, by adding recipes to model exit values
in the exit block.
As a first step, this will allow fixing #51366.

This is sort of a followup to D37310; that basically fixed the same
issue, but then the libstdc++ implementation of <atomic> changed. Re-fix
the the issue in essentially the same way: look through the addressof

Current stack size diagnostics ignore the size of the unsafe stack.
This patch attaches the size of the static portion of the unsafe stack

This reverts commit 69dd89fdcb.
This reverts commit 04000c2f92.
The current states breaks libstdc++ usage (https://reviews.llvm.org/D119136#3455423).
The fixup has been reverted as it caused other valid code to be disallowed.
I think we should start from the clean state by reverting all relevant commits.
The previous code unneccessarily duplicated the creation of a diagnostic
where the only difference was the `AssignmentAction` being passed.

STB_HIPROC and STT_HIPROC are both 15, so we can fit the symbol binding
and type in 4 bits. This gives us an additional byte to use for Symbol
flags (without increasing the type's size), which I'll be making use of
in the next diff.
Reorder type and binding based on a suggestion from @MaskRay, to
optimize st_info computation on little-endian systems (see
https://godbolt.org/z/nMn8Yar43).

Because of https://llvm.org/PR50675, we can end up producing a PLT
relocation referencing a symbol that's dropped from the dynamic symbol
table, which in turn causes a crash at runtime. We ran into this again
recently, resulting in crashes for our users. A subsequent diff will fix
that issue, but add an assert to catch it if it happens again.

WG14 has elected to remove support for K&R C functions in C2x. The
feature was introduced into C89 already deprecated, so after this long
of a deprecation period, the committee has made an empty parameter list
mean the same thing in C as it means in C++: the function accepts no
arguments exactly as if the function were written with (void) as the
parameter list.
This patch implements WG14 N2841 No function declarators without
prototypes (http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2841.htm)
and WG14 N2432 Remove support for function definitions with identifier
lists (http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2432.pdf).
It also adds The -fno-knr-functions command line option to opt into
this behavior in other language modes.

Previously constant folding uses 'dim' without checks which leads to ICE if we
do not have DIM= parameter. And for inputs without DIM= we need to form an
array of rank size with computed bounds instead of single value.
Add additional PackageConstant function to simplify 'if (dim)' handling since we
need to distinguish between scalar initialization in case of DIM= argument and
rank=1 array.
Also add a few more tests with 'parameter' type to verify folding for constant
arrays.
