This reports the full register sets to gdb, telling it about custom
offsets and sizes. It will make the gdb specific register length not
required anymore.

We also have to report architecture specific vector types and flags
that are normally builtin in gdb as it does not load them anymore when
custom register set is reported.

This makes gdb stop using its incorrect heuristics and actually request
the library list, it now correctly gets PE modules information and is
able to correctly use debug info from mixed modules.
