optimized it into a register.

This speeds up updateSSA() so it only accounts for 5% of the live range

it. It's been assumed up til now that it would be in its immediate
successor. However, this isn't necessarily the case. It could be in one of its
successor's successors.

Modify the code to more thoroughly check for an 'eh.selector' call in
successors. It only looks at a successor if we get there as a result of an
unconditional branch.

-Woverloaded-virtual shouldn't warn for static functions. Fixes rdar://9083431 & http://llvm.org/PR9396.

Add code to emulate RFE Arm instruction.

Add new instruction context for RFE instruction.

Add several new helper functions to help emulate RFE instruction
(including CurrentModeIsPrivileged, BadMode, and CPSRWriteByInstr).

  1) When we do an instantiation of the injected-class-name type,
  provide a proper source location. This is just plain good hygiene.

  2) When we're building a NestedNameSpecifierLoc from a CXXScopeSpec,
  only return an empty NestedNameSpecifierLoc if there's no
  representation.

Both problems contributed to the horrible test case in PR9390 that I
couldn't reduce down to something palatable.

Add comment.

llvm::Function argument count is not a good indicator of how many arugments does the function have at source level. If we need more space, just resize vector conservatively. This vector is only used once per function.

be next to the frame pointer or the stack pointer.

among other things:

// When stopped on breakppint 1, we can get the line entry using SBFrame API
// SBFrame.GetLineEntry().  We'll get the start address for the the line entry
// with the SBAddress type, resolve the symbol context using the SBTarget API
// SBTarget.ResolveSymbolContextForAddress() in order to get the SBSymbol.
//
// We then stop at breakpoint 2, get the SBFrame, and the the SBFunction object.
//
// The address from calling GetStartAddress() on the symbol and the function
// should point to the same address, and we also verify that.

And add one utility function disassemble(target, function_or_symbol) to lldbutil.py:

    """Disassemble the function or symbol given a target.

    It returns the disassembly content in a string object.
    """

TestDisasm.py uses the disassemble() function to do disassembly on the SBSymbol, and
then the SBFunction object.
