TESTB was implemented as AND $0xff, Rx, REGTMP. Unfortunately there
is no 3-operand AND-with-immediate instruction and so it was emulated
by the assembler using two instructions.

This CL uses CMPW instead of AND and also optimizes CMPW to use
the chi instruction where possible.

Currently these are labeled "MARK", which was accurate in the STW

marking happens for the full duration of the concurrent GC. Re-label
them as "MARK TERMINATION" to clarify this.

Currently, the process-wide GC state is attributed to the P that
happened to perform the allocation that exceeded the GC trigger. This
is pretty arbitrary and makes it hard to see when GC is running since
the GC spans are intermingled with a lot of other trace noise.

The current display is particularly confusing because it creates three
sub-rows in the P row that can overlap each other. Usually a P has
just two sub-rows: one showing the current G and another showing that
G's activity. However, because GC is attributed to a proc, it winds up
as a third row that neither subsumes nor is subsumed by any other row.
This in turn screws up the trace's layout and results in overlapping
events.

Fix these problems by creating a new dedicated row like the existing
"Network" and "Timer" rows and displaying process-wide GC events in
this row. Mark termination and sweep events still appear in their
respective P rows because these are meaningfully attributed.

When GC is disabled, we set gcpercent to -1. However, we still use
gcpercent to compute several values, such as next_gc and gc_trigger.
These calculations are meaningless when gcpercent is -1 and result in
meaningless values. This is okay in a sense because we also never use
these values if gcpercent is -1, but they're confusing when exposed to
the user, for example via MemStats or the execution trace. It's
particularly unfortunate in the execution trace because it attempts to
plot the underflowed value of next_gc, which scales all useful
information in the heap row into oblivion.

Fix this by making next_gc ^0 when gcpercent < 0. This has the
advantage of being true in a way: next_gc is effectively infinite when
gcpercent < 0. We can also detect this special value when updating the
execution trace and report next_gc as 0 so it doesn't blow up the
display of the heap line.

This CL makes minor adjustment to the handling of spaces and newlines
and then documents the result.

The semantic adjustment mainly concerns the handling of a run of
spaces following a newline in the format, like in "\n ".
Previously, that run of spaces was ignored entirely, leading to paradoxes
like the format "1 \n 2" not matching itself as input.
Now, spaces following a newline in the format match zero or more
spaces following the corresponding newline in the input.

The changes to the test suite show how minor the semantic adjustments are
and how they make the behavior more regular than previously.

This CL also updates the documentation to explain the handling of
spaces more precisely, incorporating the draft from CL 17723 but
describing the newly introduced behavior.

Anonymous pointer and slice types are very common and identical
anyway, so just reuse them rather than allocating new ones everywhere
they appear.

Turns out to be a small code/stack size win because SSA relies on
gc.Type identity for reusing temporary stack slots:

   text	   data	    bss	    dec	    hex	filename
6453005	 231643	 146328	6830976	 683b80	go.old
6446660	 231643	 146328	6824631	 6822b7	go.new
