Roll back CL making primitive type unmarshal faster,
because it broke the Unmarshal of malformed data.
Add benchmarks for unmarshal of primitive types.

We explicitly spill all parameters to the frame during initial
SSA construction. (Later passes will remove spills.)
We now properly handle local Allocs escaping via Captures.
Also: allocate BasicBlock.Succs inline.

Otherwise it's impossible to know how much data from the
json.Decoder's underlying Reader was actually consumed.
The old fix from golang.org/issue/1955 just added docs. This
provides an actual mechanism.

The dumping routine incorrectly assumed that all incoming
symbols would be non-nil and load through it to retrieve the
symbol name. Instead of using the symbol to retrieve a name,
use the name provided by the caller.

This is for SPARC64, a 64-bit processor that uses all 64-bits
of virtual addresses. The idea is to use the low order 3 bits
to at least get a small ABA counter. That should work since
pointers are aligned. The idea is for SPARC64 to set CNT_MASK
== 7, PTR_BITS == 0, PTR_MASK == 0xffffffffffffff8.
Also add uintptr casts to avoid GCC warnings. The gccgo
runtime code is compiled with GCC, and GCC warns when casting
between a pointer and a type of a different size.

net/http currently assumes that the response to a HEAD request
will always have a Content-Length header. This is incorrect.
RFC2616 says: "The HEAD method is identical to GET except that
the server MUST NOT return a message-body in the response. The
metainformation contained in the HTTP headers in response to a
HEAD request SHOULD be identical to the information sent in
response to a GET request. This method can be used for
obtaining metainformation about the entity implied by the
request without transferring the entity-body itself. This
method is often used for testing hypertext links for validity,
accessibility, and recent modification."
This means that three cases are possible: a Content-Length
header, a Transfer-Encoding header or neither. In the wild the
following sites exhibit these behaviours (curl -I):
HEAD on http://www.google.co.uk/ has Transfer-Encoding: chunked
HEAD on http://www.bbc.co.uk/ has Content-Length: 45247
HEAD on http://edition.cnn.com/ has neither header
This patch does not remove the ErrMissingContentLength error
for compatibility reasons, but it is no longer used.

This prevents the occasional issue when Mercurial screws up the locking
itself, and by moving the locking into this process we can use the
goroot for other things (such as automatically updating the builder
binary).
It also asks all builders to poll for new commits.

This function is absolutely critical for clients such as
exp/ssa, and too complex for clients to duplicate.
As with CL 7200046, gri expressed in the doc below [gophers
only] before going on leave that he intended to expose such a
predicate, though his wording suggests as an interface method
of Type rather than a standalone function. (My preference is
for binary methods to be standalone; see "On Binary Methods",
Kim Bruce, 1995). In any case if he wishes to move it that's
easily accommodated by clients.

On Windows, crypto/x509 passes through to Windows's CryptoAPI
to verify certificate chains. This method can't produce a
SystemRootsError, so make sure we always skip the test on
Windows.
This is needed because testVerify is called in both
TestGoVerify and TestSystemVerify on Windows - one is for
testing the Go verifier, the other one is for testing the
CryptoAPI verifier. The orignal CL tried to sidestep
this issue by setting systemSkip to true, but that only
affected TestSystemVerify.

further to how (I believe) it will end up being.
It is nicer to separate search from sorting functionality. Collation needs tables that
are not needed by search and vice-versa. The common functionality is separated out
in the Weigher interface. As this interface is very low-level, it will be moved to
a sub package (colltab) in a next CL.
The types that will move to this package are Weigher, Elem, and Level. The addition
of Elem allows for removing some of the duplicate code between collate and collate/build.
This CL also introduces some stubs for a higher-level API for options. The default
proposed options are quite complex and require the user to have a decent understanding
of Unicode collation. The new options hide a lot of the complexity.
