[PATCH] rs6000: __builtin_darn[_raw] should be in [power9-64] (PR103624)

[Bill Schmidt via Gcc-patches]

Hi!

PR103624 observes that we get segfaults for the 64-bit darn builtins when 
compiled
on a 32-bit architecture.  The old built-in infrastructure requires 
TARGET_64BIT, and
this was missed in the new support.  Moving these two builtins from the [power9]
stanza to the [power9-64] stanza solves the problem.

Tested the fix on a powerpc-e300c3-linux-gnu cross.  Bootstrapped and tested on
powerpc64le-linux-gnu with no regressions.  Is this okay for trunk?

Thanks!
Bill
