The fix is to have `getMemOpBaseRegImmOfs` bail out in such cases. We can possibly be more clever here, if needed. llvm-svn: 259456	2016-02-02 02:32:43 +00:00

[X86] Fix a bug in getMemOpBaseRegImmOfs

Fix a crash in `getMemOpBaseRegImmOfs` that happens if the base of
`MemOp` is a frame index memory operand.  The fix is to have
`getMemOpBaseRegImmOfs` bail out in such cases.  We can possibly be more
clever here, if needed.

[MachineSink] Don't break ImplicitNulls

Summary:
This teaches MachineSink to not sink instructions that might break the
implicit null check optimization that runs later.  This should not
affect frontends that do not use implicit null checks.
