This fixes 88 testsuite FAILs.
-mpowerpc64 does not change the ABI, but it does change the value of
UNITS_PER_WORD. We could use POINTER_SIZE_UNITS instead of 4 here,
but that does not seem quite right. This code is for SVR4 only, so
a literal 4 isn't so bad I think. Better suggestions welcome though.
Bootstrapped and tested as usual. Okay for mainline?

* config/rs6000/rs6000.c (rs6000_va_start): Use a literal 4 instead
of UNITS_PER_WORD to describe the size of stack slots.
