77365c5ed7 [dev.regabi] cmd/compile: add Name.Canonical and move Byval 
There's a bunch of code that wants to map closure variables back to
their original name, so add a single Name.Canonical method that they
can all use.

Also, move the Byval flag from being stored on individual closure
variables to being stored on the canonical variable.

Passes toolstash -cmp.

f24e40c14a [dev.regabi] cmd/compile: remove Name.Class_ accessors 
These aren't part of the Node interface anymore, so no need to keep
them around.

7d55669847 [dev.regabi] cmd/compile: simplify dwarfgen.declPos 
The previous code was way overcomplicating things. To find out if a
variable is a closure pseudo-variable, one only needs to check
IsClosureVar. Checking Captured and Byval are only meant to be used by
closure conversion.

Passes toolstash -cmp.
