(on plan 9 cc calls it log2, but that conflicts here.)
the difference is that xlog2 returns -1 on non powers of 2.
8c was rewriting /10 into /8.

* use new Make.$GOARCH files in gobuild.
* rename 6ar to arch-generic gopack.
* place objects in $GOROOT/pkg/$GOOS_$GOARCH
(makes cross-compiling easier, and no one
ever types these paths by hand anyway).

- cleanups:
- replaced internal byte buffer implementation with io.ByteBuffer (now that we have one)
- removed all uses of goto statements in favor of structured code
- converted tests into a table-driven test

likely to go back to registers for most temporaries.
most tests in lib pass. these fail:

* floating point -> integer conversions.
x86 defines that overflow/underflow
results in 1<<15, 1<<31, 1<<63 for
int16, int32, int64. when building the
unsigned conversions out of the native signed
ones, 8g turns overflow/underflow into zero.
the spec does not say what should happen.
* many tiny bug fixes. can run a large number
of files from go/test now, and can fmt.Printf.
* struggling with byte register allocation
and float32 computation.

avoid tight coupling between deferreturn and jmpdefer.
before, jmpdefer knew the exact frame size of deferreturn
in order to pop it off the stack. now, deferreturn passes
jmpdefer a pointer to the frame above it explicitly.
that avoids a magic constant and should be less fragile.

- Extend http.URLUnescape to convert '+' to space
- Add http.URLEscape
- Rename URL.Query to EncodedQuery (and stop decoding it, as decoding this field
before separating key/value pairs loses important information)
- Report a clean error on incomplete hex escapes
- Update existing tests, add new ones

auto-generated files and deletions are in another CL.
goals for new syscall:
* automate as much as possible
* do not let clients do unsafe things
* use simple types (int not int64)
* fewer files
the files are renamed from foo_amd64_linux to foo_linux_amd64,
both because it reads better (all the linux are related, all the amd64 less so)
and because it made it easier to replace the existing ones.
