[PATCH] rs6000: Fix PR92093

[Bill Schmidt]

The test case added for PR91275 fails on big-endian because 
__builtin_crypto_vpmsumd
is not a bi-endian intrinsic; source code must account for endian differences 
when
calling this intrinsic.  Fixed this and a type issue that only shows up on 
32-bit.
I thought I had previously tested this on P8 BE, but clearly not.
Tested on powerpc64-unknown-linux-gnu, committed as obvious.  Will backport 
soon.

Thanks,
Bill
