Konstantin Varlamov b85e1862c1 [libc++][hardening] Add back the safe mode. 
The safe mode is in-between the hardened and the debug modes, extending
the checks contained in the hardened mode with certain checks that are
relatively cheap and prevent common sources of errors but aren't
security-critical. Thus, the safe mode trades off some performance for
a wider set of checks, but unlike the debug mode, it can still 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.
ENABLE_STD_MODULES Whether to enable or disable building the C++23 std
modules. This variable is optional.
TODO MODULES remove when all supported compilers support
modules.
