8c3cc58d0c cmd/internal/ld: remove some dead code
Just little bits and pieces I noticed were unused in passing, and
some more found with https://github.com/opennota/check.

cdb7d7dcc2 cmd/5l etc: restore comments lost during C -> Go conversion
It appears that c2go dropped comments inside struct { ... } and enum { ... }.
Restore them.

Identified missing comments by checking for comments present
in the C code but not the Go code, made a list, and then reapplied
with some mechanical help.

175929b9fe cmd/5g etc: mechanical cleanup
Run rsc.io/grind rev 796d0f2 on C->Go conversions.

This replaces various awkward := initializations with plain var declarations.

Checked bit-for-bit compatibility with toolstash + buildall.

79f727a70e cmd/5g etc: mechanical cleanup
Run rsc.io/grind rev a26569f on C->Go conversions.

The new change in grind is the inlining of goto targets.
If code says 'goto x' and the block starting at label x is unreachable
except through that goto and the code can be moved to where
the goto is without changing the meaning of its variable names,
grind does that move. Simlarly, a goto to a plain return statement
turns into that return statement (even if there are other paths to
the return statement).

Combined, these remove many long-distance gotos, which in turn
makes it possible to reduce the scope of more variable declarations.
(Because gotos can't jump across declarations, the gotos were
keeping the declarations from moving.)

Checked bit-for-bit compatibility with toolstash + buildall.

Reduces compiler runtime in html/template by about 12%.
