dea4085da0 Remove the #ifndef NDEBUG from the FastISel debugging options. This
fixes dejagnu tests that use these options.

5be18e8476 Teach SCEVExpander to expand arithmetic involving pointers into GEP
instructions. It attempts to create high-level multi-operand GEPs,
though in cases where this isn't possible it falls back to casting
the pointer to i8* and emitting a GEP with that. Using GEP instructions
instead of ptrtoint+arithmetic+inttoptr helps pointer analyses that
don't use ScalarEvolution, such as BasicAliasAnalysis.

Also, make the AddrModeMatcher more aggressive in handling GEPs.
Previously it assumed that operand 0 of a GEP would require a register
in almost all cases. It now does extra checking and can do more
matching if operand 0 of the GEP is foldable. This fixes a problem
that was exposed by SCEVExpander using GEPs.

6679ee4e80 RecordVariable is called each time a DECLARE node is encountered. For an inlined
function, this could be many, many times. We don't want to re-add variables to
that DIE for each time. We just want to add them once. Check to make sure that
we haven't added them already.

b3a847db0b Allow the JIT ExecutionEngine to report details about the generated machine code.
Introduce a new class (MachineCodeInfo) that the JIT can fill in with details. Right now, just the address and the size of the machine code are reported.

e6abdffe06 Fix pr4202: Disable CodePlacementOpt for ARM. The ARMConstantIslandPass has
to run last because it needs to know the exact size and position of every
basic block.  Currently CodePlacementOpt is set up to run last.  It might be
worthwhile to investigate reordering these passes, but for now, let's just
make it work.

48872e0d84 Pass to verify generated machine code.
The following is checked:

* Operand counts: All explicit operands must be present.

* Register classes: All physical and virtual register operands must be
  compatible with the register class required by the instruction descriptor.

* Register live intervals: Registers must be defined only once, and must be
  defined before use.

The machine code verifier is enabled with the command-line option
'-verify-machineinstrs', or by defining the environment variable
LLVM_VERIFY_MACHINEINSTRS to the name of a file that will receive all the
verifier errors.
