Fixing a crasher bug where we were not checking for NULL before trying to retrieve the format for a type

[analyzer] add a diagnostic event when entering a call via inlining, within the callee, and add an edge.

Make sure to properly ifdef out an unused function on OSX < 10.6.  PR12136.  Patch from Jeremy Huddleston.

Clarification on the error message when the display format (eFormatBytes/eFormatBytesWithASCII) conflicts
with the byte size.

and add an erase method to it.

Patch by Andrew Craik!

Add a command and an SB API to create exception breakpoints.  Make the break output prettier for Exception breakpoints.

Make it possible for a target to mark FSUB as Expand.  This requires providing a default expansion (FADD+FNEG), and teaching DAGCombine not to form FSUBs post-legalize if they are not legal.

Safeguard against building on next OS and run on current OS.

The fpscr register contains both flags (set by FP operations/comparisons) and
control bits. The control bits (FPSCR) should be reserved, since they're always
available and needn't be defined before use. The flag bits (FPSCR_NZCV) should
like to be unreserved so they can be hoisted by MachineCSE. This fixes PR12165.

considered for inlining to 200 BBs.

Setting the max to 10 BBs introduced several false negatives, we'll
reevaluate the setting later on along with other inlining heuristics.

to escape any control characters in the message.

Teach SimpleSValBuilder that (in the absence of more information) stack memory doesn't alias symbolic memory.  This is a heuristic/hack, but works well in practice.  Fixes <rdar://problem/10978247>.

from the ASTContext.
 - Doing so requires the compiler to generate null checks against the returned
   result, but the BumpPtrAllocator never returns null pointers.
 - The optimizer can usually eliminate such checks, but not always, so this
   gives us tighter codegen in some places.
 - It would be really nice if we could just use __builtin_unreachable or
   something to tell the optimizer that the allocator never returns null, but
   LLVM isn't currently that smart.

the stub SDK to try and ensure we always pick up the right archs when they
should be able to be used.
 - Also, warn when we drop an architecture.

This is a reapplication of r150232 that should stick now that we have the
integrated assembler on for ARM.

 (a) the SystemParameters object is now passed around to the formatters; doing so enables the formatters to reuse computed values for things such as pointer-size and endianness
     instead of repeatedly computing these on their own
 (b) replacing the global ISA cache with a per-process one
 (c) providing a per-process types cache where each formatter can store the types it needs to operate, and be sure to find them the next time without recalculating them
     this also enables formatters to share types if they agree on a local naming convention
 (d) lazy fetching of data from Objective-C runtime data structures
     data is fetched as needed and we stop reading as soon as we determine that an ISA is actually garbage
