Hi, 
  I've broken this set of patches up into bite-sized chunks for easier
review and management.  They'll be showing up as replies to this
message. 
#1-6 are straightforward tests to cover the variations of the vector
load and store intrinsics. These look much alike, but there really are
differences between them. :-)
#7 touches a few existing testcases to allow continued PASSing after the
gimple folding affects codegen.
#8 introduces the actual gimple-folding for the built-ins.
#9 adds support to allow _builtin_vec_xst() to take *double or *long
long as the third parameter, where it currently only allows *vector (of
double) or *vector (of long long).  Two of the new tests will fail
without this update.

The series have been successfully regtested on Linux -
P6,P7,P8(le,be),P9. 

Thanks,
-Will
