    benchtests: Add new directive for benchmark initialization hook

    Add a new 'init' directive that specifies the name of the function to
    call to do function-specific initialization.  This is useful for
    benchmarks that need to do a one-time initialization before the
    functions are executed.

    [AARCH64] correct alignment of TLS_TCB_ALIGN (BZ #16796)

    This fixes a variety of testsuite failures for me:
    tststatic.out Error 1
    tststatic2.out Error 1
    tst-tls9-static.out Error 1
    tst-audit8.out Error 127
    tst-audit9.out Error 127
    tst-audit1.out Error 127
    and also has the added benefit of making LD_AUDIT/sotruss work on
    AArch64.

    Otherwise, we bail out early in _dl_try_allocate_static_tls as the
    alignment requirement of the PT_TLS section in libc is 16.
