Mark Mitchell 1084128584 builtins.def: Encode additional information, such as names and types, here. 
* builtins.def: Encode additional information, such as names and
	types, here.
	* builtin-types.def: New file.
	* builtins.c (built_in_names): Adjust use of DEF_BUILTIN.

	math builtins.
	(expand_builtin): Likewise.
	* c-common.c (c_common_nodes_and_builtins): Make it table-driven.
	(expand_tree_builtin): Handle long, long long, float, and long
	double variants of math functions.
	* c-common.h (c_tree_index): Remove some unused nodes.
	(void_ftype): Remove.
	(void_type_ptr): Likewise.

/* This header provides a declaritive way of describing the types that
are used when declaring builtin functions.
Before including this header, you must define the following macros:
DEF_PRIMITIVE_TYPE (ENUM, TYPE)
The ENUM is an identifier indicating which type is being defined.
TYPE is an expression for a `tree' that represents the type.
DEF_FUNCTION_TYPE_0 (ENUM, RETURN)
DEF_FUNCTION_TYPE_1 (ENUM, RETURN, ARG1)
DEF_FUNCTION_TYPE_2 (ENUM, RETURN, ARG1, ARG2)
DEF_FUNCTION_TYPE_3 (ENUM, RETURN, ARG1, ARG2, ARG3)
DEF_FUNCTION_TYPE_4 (ENUM, RETURN, ARG1, ARG2, ARG3, ARG4)
These macros describe function types. ENUM is as above. The
RETURN type is one of the enumerals already defined. ARG1, ARG2,
and ARG3 give the types of the arguments, similarly.
DEF_FUNCTION_TYPE_VAR_0 (ENUM, RETURN)
DEF_FUNCTION_TYPE_VAR_1 (ENUM, RETURN, ARG1)
DEF_FUNCTION_TYPE_VAR_2 (ENUM, RETURN, ARG1, ARG2)
Similar, but for function types that take variable arguments.
For example:
DEF_FUNCTION_TYPE_1 (BT_INT_DOUBLE, BT_INT, BT_DOUBLE)
describes the type `int ()(double)', using the enumeral
BT_INT_DOUBLE, whereas:
DEF_FUNCTION_TYPE_VAR_1 (BT_INT_DOUBLE_VAR, BT_INT, BT_DOUBLE)
describes the type `int ()(double, ...)'.
DEF_POINTER_TYPE (ENUM, TYPE)
This macro describes a pointer type. ENUM is as above; TYPE is
the type pointed to. */
