[BZ #22142] powerpc: Fix the carry bit on mpn_[add|sub]_n on POWER7

Browse Source 
Fix the ifdef clause that was being used in the opposite way, setting
a wrong value of the carry bit.

This is also correcting 2 memory accesses that were mistakenly referring
to r0 while they were supposed to mean the immediate value 0.

	[BZ #22142]
	* stdio-common/tst-printf.c (fp_test): Add tests for DBL_MAX and
	-DBL_MAX.
	(do_test): Likewise.
	* stdio-common/tst-printf.sh: Likewise.
	* sysdeps/powerpc/powerpc64/power7/add_n.S: Invert the initial
	ifdef clause in order to set the carry bit right.  Replace r0 by
	0 without changing the behavior.
