9f62600eb7 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.

the Twine was used).

of the comparison, so that the resulting expression is fully
normalized. This fixes PR9939.

48ea9389dc 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).

c77046f8d7 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.
