Make register read and write accept $<regname> as valid.
This allows:
(lldb) reg read rbx
     rbx = 0x0000000000000000
(lldb) reg read $rbx
     rbx = 0x0000000000000000
(lldb) reg write $rbx 1
(lldb) reg read $rbx
     rbx = 0x0000000000000001

to function correctly

It is not done at the RegisterContext level because we should keep the internal API clean of this user-friendly behavior and name registers appropriately.
If this ends up being needed in more places we can reconsider.

Functions in "(anonymous namespace)" was causing LLDB to crash when trying to complete a type and it would also cause functions arguments to appear in wrong place in frame display when showing function arguments.

We have the tag when figuring out the fully qualified name, append a suitable name for other types of tags when no name is available.
