Add float/vector registers for ppc64le

[alexandreyy]

Summary

Add read and write functions for VSX, VMX and float registers and fix watchpoint size

[clayborg]

Looks fine.

[alexandreyy]

@clayborg Thanks for the review.

@eugene , @labath Could you, please, commit this patch?
I don't have the permission for it.

Isn't this somewhat over-engineered?

I mean, GetVMXBuffer returns a pointer to a member variable, so it's pretty much impossible for it to be null. And all GetVMXSize does is return the size of that member variable. If we remove all this boilerplate then this becomes something like:

int regset = NT_PPC_VMX;
return NativeProcessLinux::PtraceWrapper(PTRACE_SETVRREGS, m_thread.GetID(),
                                         &regset, &m_vmx_ppc64le, sizeof(m_vmx_ppc64le));

which I think is much easier to follow than jumping through dozens of these tiny functions

[alexandreyy]

Simplified vector register methods

[alexandreyy]

Thanks @labath.
I adjusted the VSX and VMX methods.

[labath]

Thank you, I'll commit that right away.
