* emit-rtl.c (gen_rtx): Remove.

	* genattrtab.c: Don't mention gen_rtx in a comment.
	* rtl.h: Remove the prototype for gen_rtx.
	* doc/md.texi: Replace gen_rtx with gen_rtx_REG.

-**	    This routine generates an RTX of the size specified by
-**	<code>, which is an RTX code.   The RTX structure is initialized
-**	from the arguments <element1> through <elementn>, which are
-**	interpreted according to the specific RTX type's format.   The

-**	in <mode>.
-**
-**	    gen_rtx can be invoked in a way which resembles the lisp-like
-**	rtx it will generate.   For example, the following rtx structure:
-**
-**	      (plus:QI (mem:QI (reg:SI 1))
-**		       (mem:QI (plusw:SI (reg:SI 2) (reg:SI 3))))

-**		...would be generated by the following C code:
-**
-**		gen_rtx_PLUS (QImode,
-**		    gen_rtx_MEM (QImode,
-**			gen_rtx_REG (SImode, 1)),
-**		    gen_rtx_MEM (QImode,
