Do not mark no-return calls tail calls. It'll screw up special calls like longjmp and it doesn't make much sense for performance reason. If my logic is faulty, please let me know.

Even if they are suported by the core, they can be disabled

object is aligned as much as the load itself.

something totally broken and parsing them as immediates, but the .td file also
had the wrong match class so things sortof worked. Except, that is, that we
would parse
  movl $0, %eax
as
  movl 0, %eax
Feel free to guess how well that worked.

This bug was exposed by my inliner cost changes in r94615, and caused failures
of lencod on most architectures when building with LTO.

This patch fixes lencod and 464.h264ref on x86-64 (and likely others).

 - This test case is auto generated, and has been verified to round-trip
   correctly through llvm-mc by checking the assembled .o file before and after
   piping through llvm-mc. It will be extended over time as the matcher grows
   support for more instructions.

create a testcase where this matters.  The select+load transformation only
occurs when isSafeToLoadUnconditionally is true, and in those situations,
instcombine also changes the underlying objects to be aligned.  This seems
like a good idea regardless, and I've verified that it doesn't pessimize
the subsequent realignment.
