        * lang.opt: Add -fexternal-blas and -fblas-matmul-limit options.
        * options.c (gfc_init_options): Initialize new flags.
        (gfc_handle_option): Handle new flags.
        * gfortran.h (gfc_option): Add flag_external_blas and
        blas_matmul_limit flags.
        * trans-expr.c (gfc_conv_function_call): Use new argument
        append_args, appending it at the end of the argument list
        built for a function call.
        * trans-stmt.c (gfc_trans_call): Use NULL_TREE for the new
        append_args argument to gfc_trans_call.
        * trans.h (gfc_conv_function_call): Update prototype.
        * trans-decl.c (gfc_build_intrinsic_function_decls): Add
        prototypes for BLAS ?gemm routines.
        * trans-intrinsic.c (gfc_conv_intrinsic_funcall): Generate the
        extra arguments given to the library matmul function, and give
        them to gfc_conv_function_call.
        * invoke.texi: Add documentation for -fexternal-blas and
        -fblas-matmul-limit.

        * m4/matmul.m4: Add possible call to gemm routine.
        * generated/matmul_r8.c: Regenerate.
        * generated/matmul_r16.c: Regenerate.
        * generated/matmul_c8.c: Regenerate.
        * generated/matmul_i8.c: Regenerate.
