JSON decoding currently fails for null values bound to any type
which does implement the JSON Unmarshaler interface without checking
for null values (such as time.Time).
It also fails for types implementing the TextUnmarshaler interface.
The expected behavior of the JSON decoding engine in such case is
to process null by keeping the value unchanged without producing
any error.
Make sure null values are handled by the decoding engine itself,
and never passed to the UnmarshalText or UnmarshalJSON methods.

It is not clear to me what the right implementation is.
LoadReg8 and StoreReg8 are introduced during regalloc,
so after the amd64 rewrites. But implementing them
in genValue seems silly.

Bake the bit width and signedness into opcodes.
Pro: Rewrite rules become easier. Less chance for confusion.
Con: Lots more opcodes.
Let me know what you think. I'm leaning towards this, but I could be
convinced otherwise if people think this is too ugly.

Speed up the test suite by building the errors package rather than the

building doesn't matter. The errors package is smaller, and doesn't
have any assembler code.
Also make a couple of tests run in parallel.

that it blocks until GC is complete, but the re-rewrite in ed9a4c9 and

entire program and not just the caller.
Try to arrive at wording that conveys both of these properties.
