Patch for some warnings in ra-rewrite.c & ra-debug.c

[Kaveh R. Ghazi]

The patch below fixes these generic warnings:
 > ra-rewrite.c:1147: warning: signed and unsigned type in conditional expression
 > ra-rewrite.c:1233: warning: signed and unsigned type in conditional expression
 > ra-rewrite.c:1250: warning: signed and unsigned type in conditional expression

and also these on mips platforms:
 > ra-debug.c:253: warning: implicit declaration of function `mips_hard_regno_nregs'
 > ra-debug.c:280: warning: function `mips_hard_regno_nregs' was previously declared within a block

Bootstrapped on mips-sgi-irix6.2 and sparc-sun-solaris2.7.
Ok to install?

		Thanks,

	* Makefile.in (ra-debug.o): Depend on $(TM_P_H).
	* ra-debug.c: Include "tm_p.h".
	* ra-rewrite.c (is_partly_live_1): Change return type to bool.
