Will, I am guessing the recent changes that I made to the vec_neg builtin might
be getting you.  The vec_neg was orignially using P7 expansion macros but it
used P8 rtl so when compiled with -mcpu=power7 the vec_neg builtin would give
an ICE.  The macro expansions for vec_neg, vec_float2, vec_signed2 and
vec_unsigned2 are all being changed from P7 expansion macros to P8 expansion
macros to fix GCC internal compiler errors when compiled with -mcpu=power7.

See  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84422 for the list of test
cases that fail with -mcpu=power7.

The scope of the problem here seems to have changed in the last week.  
Now seeing a number of 
 " error: builtin function '__builtin_altivec_neg_v2df' requires the
'-mpower8-vector' option "
will investigate, & probably run the builtin-3 tests through a blender to sort
this out..

Yup. 
There was/is an ice in one of the builtins-3.* tests that should be better now
, per https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84422#c1

it is in my queue to re-check the results, and possibly loosen up the requires
or options on one of the tests.  I'll pursue a backport to gcc7 after I check
that over.

Will:

Here is the bug report I just got from Peter.  From our sametime
conversation sounds like you have addressed these in a recent update. 
Take a look, may be that Peter needs to update his tree

In addition to trunk this also fails with gcc 7
