cd22afa07b test: expand run.go's errorcheck, make clear which bugs run
Today, if run.go doesn't understand a test header line it just ignores
the test, making it too easy to write or edit tests that are not actually
being run.

- expand errorcheck to accept flags, so that bounds.go and escape*.go can run.
- create a whitelist of skippable tests in run.go; skipping others is an error.
- mark all skipped tests at top of file.

Update #4139.

658482d70f cmd/5g: fix register opt bug
The width was not being set on the address, which meant
that the optimizer could not find variables that overlapped
with it and mark them as having had their address taken.
This let to the compiler believing variables had been set
but never used and then optimizing away the set.

4591cd631d unicode: performance improvements (API change)
*** There is an API change here: the introduction of the
LatinOffset int in the RangeTable struct. ***

* Avoid checking Latin range multiple times for non-Latin runes.
* Use linear search when it is faster than binary search.

go test -calibrate runs the calibration for where the linear/binary
crossover should be.

benchmark                       old MB/s     new MB/s  speedup
BenchmarkFields            36.27        41.43    1.14x
BenchmarkFieldsFunc        36.23        41.38    1.14x

The speedup here is evenly split between the linear scans
and the LatinOffset change. Both are about 1.07x.

5a93fea08e vet: fix rangeloop.
In a range loop, the presence of a value implies the presence of a key.
However, the presence of a value as an *ast.Ident does not imply that
the key is also an *ast.Ident, thus leading to a panic any time the
two argument form is used where the key is not an identifier.
