Add test case.

Third pass at allowing plugins to modify default passes.  This time with a tweak so that we don't depend on an uninitialized argument.

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

- 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).

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.

Second pass at allowing plugins to modify default passes.  This time without bonus inter-library dependencies.

Fix an ARMTargetLowering::LowerSELECT bug: legalized result must have same type as input. Sorry test cases only trigger when dag combine is disabled. rdar://9449178

bool SectionLoadList::ResolveLoadAddress (addr_t load_addr, Address &so_addr) const;

Where if the address is in the last map entry, we need to look it up correctly.
My previous fix was incorrect where it looked in the first if there were
no addresses in the map that were > load_addr. Now we correctly look in the
last entry if our std::map::lower_bound search returns the end of the 
collection.

Otherwise, pass m_arch.GetMachine().
