9d4ae0ae5c gofix: handle xml.Unmarshal in xmlapi fix
This improves the handling of xml.Unmarshal in
the xmlapi fix by guessing some of the common
types used on it.

This also fixes a bug in the partial typechecker.
In an expression such as f(&a), it'd mark a as
having &T rather than *T.

316f81bb1d math/big: assembly versions of bitLen for x86-64, 386, and ARM.
Roughly 2x speedup for the internal bitLen function in arith.go.  Added TestWordBitLen test.

Performance differences against the new version of
bitLen generic:

ee9bfb023a gc: fix order of evaluation
Pulling function calls out to happen before the
expression being evaluated was causing illegal
reorderings even without inlining; with inlining
it got worse.  This CL adds a separate ordering pass
to move things with a fixed order out of expressions
and into the statement sequence, where they will
not be reordered by walk.

Replaces lvd's CL 5534079.

Fixes #2740.

6d68be46dd go/doc: clean rewrite of go/doc internals
The implementation is divided into 4 phases:
1) export filtering of an incoming AST if necessary (exports.go)
2) reading of a possibly filtered AST (reader.go: type reader)
3) method set computation (reader.go)
4) sorting and creation of final documentation (reader.go)

In contrast to the old implementation, the presentation data
(Names, Docs, Decls, etc.) are created immediately upon reading
the respective AST node. Also, all types are collected (embedded
or not) in a uniform way.

Once the entire AST has been processed, all methods and types
have been collected and the method sets for each type can be
computed (phase 3).

To produce the final documentation, the method sets and value
maps are sorted.

There are no API changes. Passes the existing test suite unchanged.

e3e1804ed2 archive/tar: fix race in TestNonSeekable
Reimplement the test based on code from adg@golang.org.

The previous version has a race since the file is closed via defer
rather than in the go routine. This meant that the file could be
closed before the go routine has actually received io.EOF. It then
receives EBADF and continues to do zero-byte writes to the pipe.

This addresses an issue seen on FreeBSD and OpenBSD, where the test
passes but exits with a SIGPIPE, resulting in a failure.

324513bc5f html: move the HTML parser to an exp/html package. The parser is a
work in progress, and we are not ready to freeze its API for Go 1.

Package html still exists, containing just two functions: EscapeString
and UnescapeString.

Both the packages at exp/html and html are "package html". The former
is a superset of the latter.

At some point in the future, the exp/html code will move back into
html, once we have finalized the parser API.

interface that covers these aspects, after Go 1.
