The current implementation doesn't resolve as per spec RFC 3986 the case
where the base URL has an opaque value, and the reference doesn't have
either a scheme, authority or path. Currently, this specific case falls
back to the "abs_path" or "rel_path" cases, where the final path results
of the base_path being resolved relatively to the reference's, but since
the opaque value is stored independently, it needs a case of its own.
The algorith for resolving references is defined in RFC 3986 section 5.2.2:

Some of the new experimental events added have a problem in that they
might be emitted during stack growth. This is, to my knowledge, the only
restriction on the tracer, because the tracer otherwise prevents
preemption, avoids allocation, and avoids write barriers. However, the
stack can grow from within the tracer. This leads to
tracing-during-tracing which can result in lost buffers and broken event
streams. (There's a debug mode to get a nice error message, but it's
disabled by default.)
This change resolves the problem by skipping writing out these new
events. This results in the new events sometimes being broken (alloc
without a free, free without an alloc) but for now that's OK. Before the
freeze begins we just want to fix broken tests; tools interpreting these
events will be totally in-house to begin with, and if they have to be a
little bit smarter about missing information, that's OK. In the future
we'll have a more robust fix for this, but it appears that it's going to
require making the tracer fully reentrant. (This is not too hard; either
we force flushing all buffers when going reentrant (which is actually
somewhat subtle with respect to event ordering) or we isolate down just
the actual event writing to be atomic with respect to stack growth. Both
are just bigger changes on shared codepaths that are scary to land this
late in the release cycle.)

Currently the traceallocfree experiment is missing info in the trace for
interpeting the produced events. Most notably, the base heap address is
missing. While not technically necessary, it is useful for getting an
accurate picture of the program's memory layout, and will be useful for
future trace experiments. Since we want to emit a batch for this, we
should also emit a batch for all the alignment info that's used to
compress the addresses (IDs) produced for the alloc/free events.
This CL distinguishes the different formats of the experimental batches
(note that there's already batches containing type information in this
experiment) by putting a byte at the beginning of each experimental
batch indicating its format.

This was removed before the latelower pass was introduced to fold
more cases of compare against zero. Add ANDconst to push the
conversion of ANDconst to ANDCCconst into latelower with the other
CC opcodes.
This also requires introducing RLDICLCC to prevent regressions
when ANDconst is converted to RLDICL then to RLDICLCC and back
to ANDCCconst when possible.

For range-over-function, the compiler generates a hidden closure
for the range body, and call the iterator function with the hidden
closure as the yield parameter. For debuggers, if it stops inside
the range body (hidden closure), it needs some way to find the
outer function (that contains the range statement), to access the
variables that are in scope. To do this, we keep the closure
pointer live on stack with a special name ".closureptr", so the
debugger can look for this name and find the closure pointer. In
the usual case, the closure is a struct defined in the outer
frame, so following the pointer it will find the frame. We do this
in SSA generation, so if the range func is inlined and there is no
actual closure, we don't generate any extra code. In the case that
there is an actual closure, it's just a single store to the stack,
so the overhead is still small.

Tests of the mutex profile focus on sync.Mutex, which is easy to
control. But since those tests still use the runtime, and contention on
internal runtime.mutex values is now also part of the mutex profile, we
have to filter out those samples before examining the profile. Otherwise
the test may be confused by stray contention on sched.lock (or other
runtime-internal locks) as a natural consequence of using goroutines.
