This isn't a suitable way of enabling a test only for one endianness,
since a test may be run with -mbig-endian or -mlittle-endian with a
compiler defaulting to the other endianness.  You need to test an
effective-target keyword instead.

Likewise.

Scanning for lots of different instructions in a testcase testing many
intrinsics doesn't do a good job of testing that each intrinsic does
the right thing, or showing where the problem is when the test starts
to fail.  I advise splitting such tests up into lots of little tests,
each testing just one intrinsic.
