a5d7c1f45e errchk: allow multiple patterns
// ERROR "pattern1" "pattern2"

means that there has to be one or more
lines matching pattern1 and then excluding
those, there have to be one or more lines
matching pattern2.  So if you expect two
different error messages from a particular
line, writing two separate patterns checks
that both errors are produced.

Also, errchk now flags lines that produce
more errors than expected.  Before, as long as
at least one error matched the pattern, all the
others were ignored.

Revise tests to expect or silence these
additional errors.

6fe82e6b96 test/bench: note changes after recent improvements to locking and runtime
Some tests are significantly faster (50%), a few are slower (up to 30%).
Fannkuch is confusing: parallel code is a little slower for gc, non-parallel and all gccgo runs are faster.

b6f0632e93 gc: correctly handle fields of pointer type to recursive forward references
Previously, whether declaring a type which copied the structure of a type it was referenced in via a pointer field would work depended on whether you declared it before or after the type it copied, e.g. type T2 T1; type T1 struct { F *T2 } would work, however type T1 struct { F *T2 }; type T2 T1 wouldn't.

507df959e4 runtime: drop chan circular linked list in favor of circular buffer
The list elements are already being allocated out of a
single memory buffer.  We can drop the Link* pointer
following and the memory it requires, replacing it with
index operations.

The change also keeps a channel from containing a pointer
back into its own allocation block, which would create a
cycle.  Blocks involved in cycles are not guaranteed to be
finalized properly, and channels depend on finalizers to
free OS-level locks on some systems.  The self-reference
was keeping channels from being garbage collected.

runtime-gdb.py will need to be updated in order to dump
the content of buffered channels with the new data structure.

Fixes #1676.

1499c78281 build: tidy intermediate files during build
This CL changes the behavior of 'make install' and 'make test'
in the src/cmd directory and the src/pkg directory to have
each recursive make clean up after itself immediately.

It does the same in test/run, removing $F.$A and $A.out
(the common byproducts) between runs.

On machines with slow disks and aggressive kernel caching,
cleaning up immediately can mean that the intermediate
objects never get written to disk.

This change eliminates almost all the disk waiting during
all.bash on my laptop (a Thinkpad X201s with an SSD running Linux).

3dbf65871c test: adjust bug324 to expect run-time failure, not compile-time.
Failing at compile time requires that for each conversion
between two interface types the compiler compare the sets of
unexported methods to see if they come from different
packages.  Since this test will fail approximately never on
real code, and since it can't catch all cases of the problem,
I don't think it's worth testing in the compiler.  This CL
changes this test to look for a run-time panic rather than a
compile-time error.

5c2666c18c gc: unsafe.Pointer is not a pointer
Change unsafe.Pointer to be its own kind of
type, instead of making it equivalent to *any.
The change complicates import and export
but avoids the need to find all the places that
operate on pointers but should not operate on
unsafe.Pointer.

Fixes #1566. (a different way)
Fixes #1582.
