* gfortran.h (gfc_expr): Add external_blas flag.
* frontend-passes.c (matrix_case): Add case A2TB2T.
(optimize_namespace): Handle flag_external_blas by
calling call_external_blas.
(get_array_inq_function): Add argument okind. If
it is nonzero, use it as the kind of argument
to be used.
(inline_limit_check): Remove m_case argument, add
limit argument instead. Remove assert about m_case.
Set the limit for inlining from the limit argument.
(matmul_lhs_realloc): Handle case A2TB2T.
(inline_matmul_assign): Handle inline limit for other cases with
two rank-two matrices. Remove no-op calls to inline_limit_check.
(call_external_blas): New function.
* trans-intrinsic.c (gfc_conv_intrinsic_funcall): Do not add
argument to external BLAS if external_blas is already set.
