GetRegisters() return a SBValueList.

SBValueList supports SBValue iteration. For example (from test/lldbutil.py),

    Returns None if there's no such kind.
    '''

    for value in registerSet:
        if kind.lower() in value.GetName().lower():
            return value

    return None

def get_GPRs(frame):
    '''Returns the general purpose registers of the frame as an SBValue.

    The returned SBValue object is iterable.  An example:
        ...
        from lldbutil import get_GPRs
        regs = get_GPRs(frame)
        for reg in regs:
            print('%s => %s' % (reg.GetName(), reg.GetValue()))
        ...
    '''
    return get_registers(frame, 'general purpose')

def get_FPRs(frame):
    '''Returns the floating point registers of the frame as an SBValue.

    The returned SBValue object is iterable.  An example:
        ...
        from lldbutil import get_FPRs
        regs = get_FPRs(frame)
        for reg in regs:
            print('%s => %s' % (reg.GetName(), reg.GetValue()))
        ...
    '''
    return get_registers(frame, 'floating point')

def get_ESRs(frame):
