Benjamin Kramer b596056413 [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.

Richard Trieu c41773ab6a 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.

Galina Kistanova f56b4f6fdd These tests require particular registered targets. Declared as such.

Dale Johannesen 2002e1f1bf Adjust a test that's expecting optimizations to be done
on MMX palignr; we don't do this for the intrinsics.

Eric Christopher 1bbc7086ff 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.

Jakob Stoklund Olesen 4d2972d793 Slightly relax test case. An upcoming LLVM commit will change the xor instruction.

Daniel Dunbar 8fbe78f6fc 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).

Nate Begeman 67dfd4236a Revert mmx palignr to use an intrinsic, since mmx shuffle patterns are missing.
