28ebc380f6 Reapply r128045 and r128051 with fixes. 
This will extend the ranges of debug info variables in registers until they are
clobbered.

Fix 1: Don't mistake DBG_VALUE instructions referring to incoming arguments on
the stack with DBG_VALUE instructions referring to variables in the frame
pointer. This fixes the gdb test-suite failure.

Fix 2: Don't trace through copies to physical registers setting up call
arguments. These registers are call clobbered, and the source register is more
likely to be a callee-saved register that can be extended through the call
instruction.

beb7e880a2 LDRT and LDRBT was incorrectly tagged as IndexModeNone during the refactorings (r119821). 
We now tag them as IndexModePost.

This fixed http://llvm.org/bugs/show_bug.cgi?id=9530.

90908a8eeb A8.6.399 VSTM: 
VFP Load/Store Multiple Instructions used to embed the IA/DB addressing mode within the
MC instruction; that has been changed so that now, for example, VSTMDDB_UPD and VSTMDIA_UPD
are two instructions.  Update the ARMDisassemblerCore.cpp's DisassembleVFPLdStMulFrm()
to reflect the change.

Also add a test case.

c11fb437b2 Add simple arg passing to MC-JIT and support for exit() call. 
Support argument passing simple, common, prototypes directly. More
complicated scenarios will require building up a stub function, which the
MC-JIT isn't set up to handle yet.

Add Intercept.cpp, which is just a copy from ExecutionEngine/JIT for now,
to handle looking looking up external symbol names. This probably more
properly belongs as part of RuntimeDyld. It'll migrate there as things
flesh out more fully.

e19f7261d5 Hook up the MCJIT to the RuntimeDyld library. 
Lots of cleanup to make the interfaces prettier, use the JITMemoryManager,
handle multiple functions and modules, etc.. This gets far enough that
the MCJIT compiles and runs code, though.

fc9e8a04c3 Dont emit 'DBG_VALUE %noreg, ...' to terminate user variable ranges. 
These ranges get completely jumbled by the post-ra scheduler, and it is not
really reasonable to expect it to make sense of them.

Instead, teach DwarfDebug to notice when user variables in registers are
clobbered, and terminate the ranges there.
