15436da232 crypto/md5: faster inner loop, 3x faster overall
The speedup is a combination of unrolling/specializing
the actual code and also making the compiler generate better code.

Go 1.0.1 (size: 1239 code + 320 data = 1559 total)
md5.BenchmarkHash1K   1000000	   7178 ns/op	 142.64 MB/s
md5.BenchmarkHash8K    200000	  56834 ns/op	 144.14 MB/s

Partial unroll  (size: 1115 code + 256 data = 1371 total)
md5.BenchmarkHash1K   5000000	   2513 ns/op	 407.37 MB/s
md5.BenchmarkHash8K    500000	  19406 ns/op	 422.13 MB/s

Complete unroll  (size: 1900 code + 0 data = 1900 code)
md5.BenchmarkHash1K   5000000	   2442 ns/op	 419.18 MB/s
md5.BenchmarkHash8K    500000	  18957 ns/op	 432.13 MB/s

Comparing Go 1.0.1 and the complete unroll (this CL):

benchmark               old MB/s     new MB/s  speedup
md5.BenchmarkHash1K       142.64       419.18    2.94x
md5.BenchmarkHash8K       144.14       432.13    3.00x

On the same machine, 'openssl speed md5' reports 441 MB/s
and 531 MB/s for our two cases, so this CL is at 90% and 80% of
those speeds, which is at least in the right ballpark.
OpenSSL is using carefully engineered assembly, so we are
unlikely to catch up completely.

Measurements on a Mid-2010 MacPro5,1.

f26d61731d go/parser: fix comment grouping (day 1 bug)
Comment groups must end at the end of a line (or the
next non-comment token) if the group started on a line
with non-comment tokens.

This is important for correct computation of "lead"
and "line" comments (Doc and Comment fields in AST nodes).

Without this fix, the "line" comment for F1 in the
following example:

type T struct {
     F1 int // comment1
     // comment2
     F2 int
}

is "// comment1// comment2" rather than just "// comment1".

This bug was present from Day 1 but only visible when
looking at export-filtered ASTs where only comments
associated with AST nodes are printed, and only in rare
cases (e.g, in the case above, if F2 where not exported,
godoc would show "// comment2" anyway because it was
considered part of the "line" comment for F1).

The bug fix is very small (parser.go). The bulk of the
changes are additional test cases (parser_test.go).

The fix exposed a caching bug in go/printer via one of the
existing tests, hence the changes to printer.go.

As an aside, the fix removes the the need for empty lines
before an "// Output" comment for some special cases of
code examples (e.g.: src/pkg/strings/example_test.go, Count
example).

No impact on gofmt formatting of src, misc.

Fixes #3139.

ec099b2bc7 exp/locale/collate: implementation of main collation functionality for
key and simple comparisson. Search is not yet implemented in this CL.
Changed some of the types of table_test.go to allow reuse in the new test.
Also reduced number of primary values for illegal runes to 1 (both map to
the same).

6dfe0162a6 misc/chrome/gophertool: lower CL number's lower bound and fix input focus on Mac
As our CL number could be as small as 152046, changed CL number's lower bound
to 150000. Hopefully our issue count won't reach 150000 any time soon.
Chrome on Mac OS X has very strange behavior regarding the focus, although we
force the focus to the input box on load, the page still come up with focus on
"issue". Set the tabindex of the input box as a workaround.
