  [lldb] Add "register info" command

This adds a new command that will show all the information lldb
knows about a register.
```
(lldb) register info s0
       Name: s0
       Size: 4 bytes (32 bits)
Invalidates: v0, d0
  Read from: v0
    In sets: Floating Point Registers (index 1)
```

Currently it only allows a single register, and we get the
information from the RegisterInfo structure.

For those of us who know the architecture well, this information
is all pretty obvious. For those who don't, it's nice to have it
at a glance without leaving the debugger.

I hope to have more in depth information to show here in the future,
which will be of wider use.
