	* jit/jit-rules-alpha.c: register class should not include FIXED
	registers.

	* .cvsignore, tools/.cvsignore, tutorial/.cvsignore: updated
	the .cvsignore files to ignore some generated files.

want to skip the @code{return} statement.  We achieve this with the
@code{jit_insn_branch_if_not} instruction:

@example
jit_label_t label1 = jit_label_undefined;
...
jit_insn_branch_if_not(function, temp1, &label1);
@end example

The label must be initialized to @code{jit_label_undefined}.  It will be
updated by @code{jit_insn_branch_if_not} to refer to a future position in
the code that we haven't seen yet.

If the condition is true, then execution falls through to the next
instruction where we return @code{x} to the caller:

@example
jit_insn_return(function, x);
@end example

If the condition was not true, then we branched to @code{label1} above.
