[CodeGen] Flip lanes when lowering __builtin_palignr with one lane
...
Otherwise we'd pick the wrong lane for the resulting shuffle and
miscompile code. PR24187.

Revision 139454 fixed a broken assert in LLVM, which causes
...
a test failure in CodeGen/palignr.c, which has been marked
XFAIL for the time being. A bug has been filed at PR10901
for this issue.

Adjust a test that's expecting optimizations to be done

on MMX palignr; we don't do this for the intrinsics.

Rewrite handling of 64-bit palignr intrinsics to be vector shuffles.
...
Stop multiplying constant by 8 accordingly in the header and change
intrinsic definition for what types we expect.
Add to existing palignr test to check that we're emitting the correct things.

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
...
- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
