Anna Zaks b1d3d96872 [analyzer] Make CoreEngine responsible for enqueueing Stmt Nodes. 
Enqueue the nodes generated as the result of processing a statement
inside the Core Engine. This makes sure ExpEngine does not access
CoreEngine's private members and is more concise.

Chad Rosier a486f44733 Add a TODO comment. FastISel works by parsing each basic block from the bottom 
up.  Thus, improving the support for compares is goodness because it increases
the number of terminator instructions we can handle.  This creates many more 
opportunities for target specific fast-isel.

Johnny Chen 66d362e9bf Establish a baseline for bench.py score by using a fixed lldb executable as the 
inferior program for the lldb debugger to operate on.  The fixed lldb executable
corresponds to r142902.

Plus some minor modifications to the test benchmark to conform to way bench.py
is meant to be invoked.

We were parsing label references to the i12 encoding, which isn't right.
They need to go to the pci variant instead.

Rafael Espindola f5a15529a7 Run test with -verify-machineinstrs. 
Patch by Sanjoy Das.

Sean Callanan d2cb626ac1 Extended the IR interpreter to handle the variables 
"_cmd", "this", and "self".  These variables are handled
differently from all other external variables used by
the expression.  Other variables are used indirectly
through the $__lldb_arg operand; only _cmd, this, and
self are passed directly through the ABI.

There are two modifications:

 - I added a function to ClangExpressionDeclMap that
   retrives the value of one of these variables by name;
   and

 - I made IRInterpreter fetch these values when needed,
   and ensured that the proper level of indirection is
   used.

Rafael Espindola 66393c127d This commit introduces two fake instructions MORESTACK_RET and 
MORESTACK_RET_RESTORE_R10; which are lowered to a RET and a RET
followed by a MOV respectively.  Having a fake instruction prevents
the verifier from seeing a MachineBasicBlock end with a
non-terminator (MOV).  It also prevents the rather eccentric case of a
MachineBasicBlock ending with RET but having successors nevertheless.

Patch by Sanjoy Das.

Rafael Espindola c594135b68 Fix pr9614 by not emitting an available_externally function when it calls

available_externally functions are supposed to correspond to an external
