Greg Clayton 3f5c08f5c2 Added a function to lldb_private::Address: 
addr_t
        Address::GetCallableLoadAddress (Target *target) const;
        
This will resolve the load address in the Address object and optionally
decorate the address up to be able to be called. For all non ARM targets, this
just essentially returns the result of "Address::GetLoadAddress (target)". But
for ARM targets, it checks if the address is Thumb, and if so, it returns
an address with bit zero set to indicate a mode switch to Thumb. This is how
we need function pointers to be for return addresses and when resolving 
function addresses for the JIT. It is also nice to centralize this in one spot
to avoid having multiple copies of this code.

Dan Gohman 3268e4d692 When forming an ICmpZero LSRUse, normalize the non-IV operand 
of the comparison, so that the resulting expression is fully
normalized. This fixes PR9939.

Alexis Hunt d0cdd1fab1 Revert r121528 as it breaks a simple testcase, which leads to, among 
other things, libcxx not building.

Charles Davis 77e0610d7c 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).

Stuart Hastings 51d696766c 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.

Greg Clayton 1c870d6e9f One more fix to: 
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.
