varconst f0dfe682bc [libc++][hardening] Deprecate _LIBCPP_ENABLE_ASSERTIONS. 
`_LIBCPP_ENABLE_ASSERTIONS` was used to enable the "safe" mode in
libc++. Libc++ now provides the hardened mode and the debug mode that
replace the safe mode.

For backward compatibility, enabling `_LIBCPP_ENABLE_ASSERTIONS` now
enables the hardened mode. Note that the hardened mode provides
a narrower set of checks than the previous "safe" mode (only
security-critical checks that are performant enough to be used in
production).

Usage:
${PROGNAME} [options] <BUILDER>
[-h|--help] Display this help and exit.
--llvm-root <DIR> Path to the root of the LLVM monorepo. By default, we try
to figure it out based on the current working directory.
--build-dir <DIR> The directory to use for building the library. By default,
this is '<llvm-root>/build/<builder>'.
--osx-roots <DIR> Path to pre-downloaded macOS dylibs. By default, we download
them from Green Dragon. This is only relevant at all when
running back-deployment testing if one wants to override
the old dylibs we use to run the tests with different ones.
Environment variables
CC The C compiler to use, this value is used by CMake. This
variable is optional.
CXX The C++ compiler to use, this value is used by CMake. This
variable is optional.
CMAKE The CMake binary to use. This variable is optional.
CLANG_FORMAT The clang-format binary to use when generating the format
ignore list.
GIT_CLANG_FORMAT The git-clang-format binary to use in the 'format' builder.
When the value is omitted, it defaults to
'git-clang-format'. This variable or its fallback must work
when running the 'format' builder.
ENABLE_CLANG_TIDY Whether to compile and run clang-tidy checks. This variable
is optional.
