The go/build package needs access to this configuration,
so move it into a new package available to the standard library.

Move Flag, Debug, Ctxt, Exit, and error messages to
new package cmd/compile/internal/base.
These are the core functionality that everything in gc uses
and which otherwise prevent splitting any other code
out of gc into different packages.
A minor milestone: the compiler source code
no longer contains the string "yy".

Part 1: CL 199499 (GOOS nacl)
Part 2: CL 200077 (amd64p32 files, toolchain)
Part 3: stuff that arguably should've been part of Part 2, but I forgot
one of my grep patterns when splitting the original CL up into
two parts.
This one might also have interesting stuff to resurrect for any future
x32 ABI support.

Now only cmd/asm and cmd/compile depend on cmd/internal/obj. Changing
the assembler backends no longer requires reinstalling cmd/link or
cmd/addr2line.
There's also now one canonical definition of the object file format in
cmd/internal/objabi/doc.go, with a warning to update all three
implementations.
objabi is still something of a grab bag of unrelated code (e.g., flag
and environment variable handling probably belong in a separate "tool"
package), but this is still progress.
Fixes #15165.
Fixes #20026.

This CL changes the GOARCH.Init functions to take gc.Thearch as a
parameter, which gc.Main supplies.
Additionally, the x86 backend is refactored to decide within Init
whether to use the 387 or SSE2 instruction generators, rather than for
each individual SSA Value/Block.
Passes toolstash-check -all.

As cmd/internal/obj is coordinating the definition of GOOS, GOARCH,
etc across the compiler and linker, turn its functions into globals
and use them everywhere.

s390x does not require duffzero/duffcopy since it has
storage-to-storage instructions that can copy/clear up to 256
bytes at a time.
peep contains several new passes to optimize instruction
sequences that match s390x instructions such as the
compare-and-branch and load/store multiple instructions.
copyprop and subprop have been extended to work with moves that
require sign/zero extension. This work could be ported to other
architectures that do not used sized math however it does add
complexity and will probably be rendered unnecessary by ssa in
the near future.

This is a subset of https://golang.org/cl/20022 with only the copyright
header lines, so the next CL will be smaller and more reviewable.
Go policy has been single space after periods in comments for some time.
The copyright header template at:
https://golang.org/doc/contribute.html#copyright
also uses a single space.
Make them all consistent.

Trivial merging of 5g, 6g, ... into go tool compile,
and similarlly 5l, 6l, ... into go tool link.
The files compile/main.go and link/main.go are new.
Everything else in those directories is a move followed by
change of imports and package name.
This CL breaks the build. Manual fixups are in the next CL.
See golang-dev thread titled "go tool compile, etc" for background.
