Silence texinfo 5.1 warnings

This patch silences texinfo 5.1 warnings by using @subsection and
sorting entries in Machine Dependencies menu.

	* doc/as.texinfo (Bundle directives): Shorten menu entry and
	use @subsection.
	(CFI directives): Use @subsection.
	(SH-Dependent, SH64-Dependent): Moved after SCORE-Dependent.
	* doc/c-i386.texi (i386-Mnemonics): Use @subsection.

 @code{.cfi_def_cfa_offset} modifies a rule for computing CFA. Register

 absolute offset that will be added to a defined register to compute
 CFA address.

 Previous value of @var{register} is saved at offset @var{offset} from
 the current CFA register.  This is transformed to @code{.cfi_offset}
 using the known displacement of the CFA register from the CFA.
 This is often easier to use, because the number will match the
 code it's annotating.
