Add TestDisasmAPI.py which exercises the newly added SBFunction/SBSymbol.GetStartAddress(),

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.
