Committed as revision 135299.

Added comments by Eric from

Undid patch from Adam Nemet as discussed in thread 
http://gcc.gnu.org/ml/gcc-patches/2008-05/msg00830.html

Bootstraped again on x86-64 to make sure there was no patch rot.

    * optabs.c (prepare_cmp_insn): Changed LCT_PURE_MAKE_BLOCK to
    LCT_PURE and LCT_CONST_MAKE_BLOCK to LCT_CONST in calls to
    emit_library_call_value.
    * builtins.c (expand_builtin_powi, expand_builtin_memcmp): Ditto.
    * tree.h (ECF_LIBCALL_BLOCK): Removed.
    * calls.c (initialize_argument_information, precompute_arguments,
    expand_call, emit_library_call_value_1): Remove ECF_LIBCALL_BLOCK.
    (precompute_arguments): Removed flags parameter.
    * rtl.h (LCT_CONST_MAKE_BLOCK, LCT_PURE_MAKE_BLOCK): Removed.
