These don't use any flags in TestMain itself, so the call is redundant
as M.Run will do it.

This change makes sure that tests are run with the correct
version of the go tool. The correct version is the one that
we invoked with "go test", not the one that is first in our path.

Moving so that new Go 1.4 pprof can use it.
The old 'GNU objdump workalike' mode for 'go tool objdump'
is now gone, as are the tests for that mode. It was used only
by pre-Go 1.4 pprof. You can still specify an address range on
the command line; you just get the same output format as
you do when dumping the entire binary (without an address
limitation).

This removes a bunch of ugly duplicate code.
The end goal is to factor the disassembly code

For Go 1.3 these external packages were collapsed into
large single-file implementations stored in the cmd/objdump
directory.
For Go 1.4 we want pprof to be able to link against them too,
so move them into cmd/internal, where they can be shared.
The new files are copied from the repo in the file path (rsc.io/...).
Those repos were code reviewed during development
(mainly by crawshaw and minux), because we knew the
main repo would use them.

Fixes objdump test (and therefore build) on ELF systems.
While we're here, fix bounds on gnuDump so that we
don't crash when asked to disassemble outside
the text segment. May fix Windows build or at least

Update #7452
This is the basic logic needed for objdump, and it works well enough
to support the pprof list and weblist commands. A real disassembler
needs to be added in order to support the pprof disasm command
and the per-line assembly displays in weblist. That's still to come.
Probably objdump will move to go.tools when the disassembler
is added, but it can stay here for now.
