	* Makefile.in: Regenerate.
	* all files in generated/: Regenerate.

	* f95-lang.c (DO_DEFINE_MATH_BUILTIN): Add support for long
	double builtin function.
	(gfc_init_builtin_functions): Add mfunc_longdouble,
	mfunc_clongdouble and func_clongdouble_longdouble trees. Build
	them for round, trunc, cabs, copysign and pow functions.
	* iresolve.c (gfc_resolve_reshape, gfc_resolve_transpose): Add
	case for kind 10 and 16.
	* trans-decl.c: Add trees for cpowl10, cpowl16, ishftc16,
	exponent10 and exponent16.
	(gfc_build_intrinsic_function_decls): Build nodes for int16,
	real10, real16, complex10 and complex16 types. Build all possible
	combinations for function _gfortran_pow_?n_?n. Build function
	calls cpowl10, cpowl16, ishftc16, exponent10 and exponent16.
	* trans-expr.c (gfc_conv_power_op): Add case for integer(16),
	real(10) and real(16).
	* trans-intrinsic.c: Add suppport for long double builtin
	functions in BUILT_IN_FUNCTION, LIBM_FUNCTION and LIBF_FUNCTION
	macros.
	(gfc_conv_intrinsic_aint): Add case for integer(16), real(10) and
	real(16) kinds.
	(gfc_build_intrinsic_lib_fndecls): Add support for real10_decl
	and real16_decl in library functions.
	(gfc_get_intrinsic_lib_fndecl): Add cases for real and complex
	kinds 10 and 16.
	(gfc_conv_intrinsic_exponent): Add cases for real(10) and real(16)
	kinds.
	(gfc_conv_intrinsic_sign): Likewise.
	(gfc_conv_intrinsic_ishftc): Add case for integer(16) kind.
	* trans-types.c (gfc_get_int_type, gfc_get_real_type,
	gfc_get_complex_type, gfc_get_logical_type): Doesn't error out in
	the case of kinds not available.
	* trans.h: Declare trees for cpowl10, cpowl16, ishftc16,
	exponent10 and exponent16.

	* gfortran.dg/large_real_kind_2.F90: New test.
	* gfortran.dg/large_integer_kind_2.f90: New test.
