I added a new file ARMAsmBackend which stubs out in similar ways to
the eqv X86 class.
For now, I split the ELFARMAsmBackend from the DarwinARMAsmBackend
(also mimicking X86)

or not. TableGen needs to generate the printInstruction() function as taking
an MCInstr* or a MachineInstr*, depending. Default to the old non-MC
version so that everything not yet using MC continues to just work without
fidding.

Removed CPLUSPLUSFLAGS which is simply wrong and CPPFLAGS which is unnecessary.

- Idempotent operations are on by default, to match --analyze in the driver.
- Integrated stats calculation based on parsing warnings emitted with the -analyzer-stats flag. The new -stats flag enables this.
- New -maxloop flag to pass down a maxloop value to the analyzer.

1. Cortex-a9 8-bit and 16-bit loads / stores AGU cycles are 1 cycle longer than 32-bit ones.
2. Cortex-a9 is out-of-order so model all read cycles as cycle 1.
3. Lots of other random fixes for A8 and A9.

Change CheckerVisitor so that [Pre,Post]VisitCallExpr only handles CallExprs for simple C functions, not
all CallExprs (including CXXMemberCallExpr, etc.).  Now the generic handler for all CallExprs is [Pre,Post]VisitGenericCallExpr.

Also add [Pre,Post]Visit hooks for CXXMemberCallExpr.

Change GRExprEngine::VisitCXXMemberCallExpr() to do pre/post checker visits of the call.

In MeasureTokenLength, the FileLoc supplied to the lexer must point to the start of the buffer, or we risk overflow.

- Use BlockEntrance rather than BlockEdge to bring in line with UnreachableCodeChecker. Fixes an issue where unreached blocks would still be counted as reachable.
- Added warnings for all BlockAborted locations. This allows us to see where the analyzer stopped analyzing.

Modified the ccc-analyzer script to print the compiler command when log level verbosity is enabled. This is handy for debugging.

Change -analyzer-max-nodes to allow 0 as a parameter. This allows the analyzer to completely analyze a worklist regardless of time taken.

Early CFG simplification can fold conditionals down to selects, which is often a good thing, but it can also
hide jump threading opportunities by turning control flow into data flow.  Run an early JumpThreading pass
(adds approximately an additional 1% to optimization time on SPEC), allowing it to get a shot at these cases
first.  Fixes <rdar://problem/8447345>.
