This is a follow up to rev 443a32e707 which reduces some of the
duplication between methods and functions that operate on obj.Biobuf.
obj.Biobuf has Flush and Write methods as well as helpers which duplicate
those methods, consolidate on the former and remove the latter.
Also, address a final comment from CL 9525.

This lets us avoid loading string constants via the GOT and (together with
http://golang.org/cl/9102) results in the fannkuch benchmark having very similar
register usage with -dynlink as without.

This reduces the number of allocations in the compiler
while building the stdlib by 15.66%.
No functional changes. Passes toolstash -cmp.

They don't really make any sense on this side of the compiler/linker divide.
Some of the code touching these fields was the support for R_TLS when
thechar=='6' which turns out to be dead and so I just removed all of that.

In addition to possibly being clearer code,
this replaces an O(n) lookup with an O(log n) lookup.

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.

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.

Ran rsc.io/grind rev 6f0e601 on the source files.
The cleanups move var declarations as close to the use
as possible, splitting disjoint uses of the var into separate
variables. They also remove dead code (especially in
func sudoaddable), which helps with the var moving.
There's more cleanup to come, but this alone cuts the
time spent compiling html/template on my 2013 MacBook Pro
from 3.1 seconds to 2.3 seconds.

This CL adds the real cmd/internal/obj packages.
Collectively they correspond to the liblink library.
The conversion was done using rsc.io/c2go's run script
at rsc.io/c2go repo version 706fac7.
This is not the final conversion, just the first working draft.
There will be more updates, but this works well enough
to use with go tool objwriter and pass all.bash.
