The linker currently (on some platforms) takes a -shared flag, which means
approximately what -buildmode=c-shared means in the in the proposed "Go
Execution Modes" document. As part of implementing other modes, the term
"shared" becomes horribly overloaded, so this replaces -shared with a
-buildmode argument instead (which currently only handles -buildmode=c-shared
and the default -buildmode=exe -- no new behaviour here).
As the linker support for -shared was in 1.4 this retains it as an alias.

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.

The creation of liblink and subsequent introduction of more explicit
TLS handling broke 6l's (unsupported) -shared flag. This change adds
-shared flags to cmd/asm and 6g and changes liblink to generate shared-
library compatible instruction sequences when they are passed, and
changes 6l to emit the appropriate ELF relocation.
A proper fix probably also requires go tool changes.
Fixes#9652.

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%.

mv cmd/new5l cmd/5l and so on.
Minimal changes to cmd/dist and cmd/go to keep things building.
More can be deleted in followup CLs.
