There is no need to maintain a set to keep track of variables that use location expressions. In such cases, AT_location attribute's value will be a label.

Enforce the constraint that Rt must be even on LDRD/STRD instructions in ARM mode.  Update tests to reflect this fact.

When a variable is inlined multiple places, abstract variable keeps name, location, type etc.. info and all other concreate instances of the variable directly refers to abstract variable.

This builds off of the current scheme, but instead of llvm.eh.exception and
llvm.eh.selector, it uses the landingpad instruction. And instead of
llvm.eh.resume, it uses the resume instruction.

Because of the invariants in the landing pad instruction, a lot of code that's
currently needed to find the appropriate intrinsic calls for an invoke
instruction won't be needed once we go to the new EH scheme. The "FIXME"s tell
us what to remove after we switch.

Apparently we never added code to expand these pseudo instructions, and in
over a year, no one has noticed.  Our register allocator must be awesome!

This caused a race condition where a thread calls ~LLVMContextImpl which calls
Module::dropAllReferences which calls begin() on an empty ilist that would
create the sentinel, which racily accesses the global context.

This can not be fixed by locking inside createSentinel because the lock would
need to be shared with all users of the global context, including those that
reside outside LLVM's own code.

Note that this change affects the existing non-atomic load and store
instructions; the parser now accepts both forms, and the change is noted
in the release notes.

Tidy up the code a bit and push the definition of the value next to the uses
to try to minimize this sort of issue from arising again while I'm at it.
