    powerpc: POWER7 optimizations

    Add optimizations for classification functions (32-bit and 64-bit) and
    string functions (32-bit and 64-bit).

    powerpc: Re-work the Implies structure

    This patch tries to organize the implies files for ppc, since there are
    a number of processors and most of them are compatible with each other
    (backwards compatible).

    Having in mind that we start the search for processor-specific files in
    the sysdeps/unix/sysv/linux tree
    (sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/[processor]/fpu to be
    exact), we would like to grab any linux-specific code from that tree
    prior to going through the other tree (sysdeps/powerpc/...).

    For that, i removed the Implies files that were originally inside the
    fpu directories and placed then in the non-fpu directories (still inside
    the unix/sysv/linux tree). If no processor-specific/linux-specific files
    could be found, we "imply" the other tree's (sysdeps/powerpc/...) fpu
    directory for that specific processor AND also the non-fpu directory for
    that same tree.

    If, again, no processor-specific code is found, we read another Implies
    file that will point to the most compatible processor that we should
    grab code from, and so on, until we reach the power4 processor.

    So, in summary, the Implies files will live inside these directories
    now:

    * sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/[processor]
    * sysdeps/powerpc/powerpc[32|64]/[processor]

    Practical example of the order we will use to pick power6-specific code
    with the new structure.

    sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/power6/fpu ->
    sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/power6 ->
    sysdeps/powerpc/powerpc[32|64]/power6/fpu ->
    sysdeps/powerpc/powerpc[32|64]/power6 ->
    sysdeps/powerpc/powerpc[32|64]/power5+/fpu ->
    sysdeps/powerpc/powerpc[32|64]/power5+ ->
    sysdeps/powerpc/powerpc[32|64]/power5/fpu ->
    sysdeps/powerpc/powerpc[32|64]/power5 ->
    sysdeps/powerpc/powerpc[32|64]/power4/fpu ->
    sysdeps/powerpc/powerpc[32|64]/power4 (from here, it'll go to the
    generic path as usual)

Restore locking in free_check.

This code is only used when MALLOC_CHECK_ is used. Then some bogus
crashes and/or assert could result from the locking changes. The code
ain't fast.
