destructors is clang 10 and the oldest one that accepts -std=c++2a is 5,
so mark these as UNSUPPORTED for clang-5 to clang-9.

Define all the fuzzing tests in libcxx/test/libcxx/fuzzing, and get
rid of the ad-hoc libcxx/fuzzing directory, which wasn't properly
integrated with the build system or test suite.

As a fly-by change, this also reduces the dependencies of fuzzing tests
on large library components like <iostream>, to make them work on more
platforms.

Fixes a number of stage2 buildbots that were failing when I generalized the m_ConstantInt() logic - that didn't match for pointer types but m_Zero() does......

Allow logging final rewards. A final reward is logged only once, and is
serialized as all-zero values, except for the last one.

Previously, we would define new/delete in both libc++ and libc++abi.
Not only does this cause code bloat, but also it's technically an ODR
violation since we don't know which operator will be selected. Furthermore,
since those are weak definitions, we should strive to have as few of them
as possible (to improve load times).

My preferred choice would have been to put the operators in libc++ only
by default, however that would create a circular dependency between
libc++ and libc++abi, which GNU linkers don't handle.

Folks who want to ship new/delete in libc++ instead of libc++abi are
free to do so by turning on LIBCXX_ENABLE_NEW_DELETE_DEFINITIONS at
CMake configure time.

On Apple platforms, this shouldn't be an ABI break because we re-export
the new/delete symbols from libc++abi. This change actually makes libc++
behave closer to the system libc++ shipped on Apple platforms.

On other platforms, this is an ABI break for people linking against libc+...

... in `<numbers>` tests with `[[maybe_unused]]`.

I did some profiling of lit while trying to optimize the libc++ test
startup for remote hosts and it turns out that there is a realpath() call
for every message printed and this shows up in the profile.
The inspect.getframeinfo() function calls realpath() internally and
moreover we don't need most of the other information returned from it.
This patch uses inspect.getsourcefile() and os.path.abspath() to remove
../ from the path instead. Not resolving symlinks reduces the startup time
for running a single test with lit by about 50ms for me.

Causing stage2 build failures on some bots.

Added option `ScopedEnumConstant(Prefix|Case|Suffix)` to readability-identitied-naming.
This controls the style for constants in scoped enums, declared as enum (class|struct).
If this option is unspecified the EnumConstant style will be used instead.

This addressed post commit comments for D89391.

The current situation/behavior is:
1) llvm-readelf doesn't need a string that is specified by `DT_SONAME`.
2) llvm-readobj/elf always tries to read it, even when there is no `DT_SONAME` tag.
3) Because of that both tools reports a warning for many our test cases.

This patch delays getting a SOName string and changes the behavior (llvm-readobj) to
only report a warning when there is a `DT_SONAME` and a string cab't be read.
Warning is not reported for llvm-readelf, as it never tries to dump it.

The current BufferPlacement transformation contains several concepts for
hoisting allocations. However, more advanced hoisting techniques should not be
integrated into the BufferPlacement transformation. Hence, this CL refactors the
current BufferPlacement pass into three separate pieces: BufferDeallocation and
BufferAllocation(Loop)Hoisting. Moreover, it extends the hoisting functionality
by allowing to move allocations out of loops.
