PATCH [0/2] Convert unavailable vector to be bit, not byte, based.

This patch set is inspired by two previous patches I've posted:

https://sourceware.org/ml/gdb-patches/2013-08/msg00305.html
https://sourceware.org/ml/gdb-patches/2013-08/msg00309.html

but I think can exist as a separate piece of work.

The vector of unavailable parts of a value is currently byte based.
Given that we can model a value down to the bit level, we can
potentially loose information with the current implementation. After
the patch we model the unavailable information in bits.

Tested on x86-64 linux, including against native gdbserver.

Thanks,
Andrew
