[patch] Remove loop notes (1/8) -- comment in shorten branches

[Zdenek Dvorak]

Hello,

this is the first of the patches to remove loop notes.  This one
just removes an outdated comment in final.c:shorten_branches,
and make it more obvious we ignore normal insns.

Bootstrapped & regtested on i686.

Zdenek

	* final.c (shorten_branches): Remove outdated comment, and turn
	the if branch that guards it to continue.
