6fcb6e454b Revert r128961 because it didn't include a test and causes the verifier to fail 
on CodeGen/X86/2007-05-07-InvokeSRet.ll. There is probably a bug here that was
fixed by r128961, but since there is no test or reference to a source file I have
to revert it.

6fd5a6000b Make the demanded bits/elements optimizations preserve debug line information. 
I'm not sure this is quite ideal, but I can't really think of any better way to do it.

f07090134d Add some more Win64 EH directives: 
- StartChained and EndChained delimit a chained unwind area, which can contain
  additional operations to be undone if an exception occurs inside of it.
- UnwindOnly declares that this function doesn't handle any exceptions. If it
  has a handler, it's an unwind handler instead of an exception handler.
- Lsda declares the location and size of the LSDA, which in the Win64 EH
  scheme is kept inside the UNWIND_INFO struct. Windows itself ignores the
  LSDA; it's used by the Language-Specific Handler (the "Personality Function"
  from DWARF).

1f2cb9824d An imminent fix to the x86_64 byval logic will expose a flaw in the 
x86_64 sibcall logic.  I've filed PR9943 for the sibcall problem, and
this patch alters the testcase to work around the flaw.  When PR9943
is fixed, this patch should be reverted.
