[v3] Fully preprocessorify TR1 tuples

[Doug Gregor]

Hi folks,

The TR1 function objects are fully preprocessor-based, so that  
tweaking the "repeat.h" and "bind_repeat.h" headers allow us to  
change the maximum number of parameter supported. TR1 tuples were 95%  
of the way there; this patch finishes the job. The two Perl scripts  
are used to generate repeat.h and bind_repeat.h; I'm including them  
in the e-mail for archival purposes, to make it easier to change the  
number of support parameters later.

Test powerpc-apple-darwin8.8.0; no regressions.

	Cheers,
	Doug
