This improves the short version of the writer test.
First of all, it has a much quicker setup. Previously that
could take up towards 0.5 second.
Secondly, it will test all compression levels in short mode as well.
Execution time is 1.7s/0.03s for normal/short mode.

This reverts commit ab4c9298b8.
Sysmon critically depends on system timer resolution for retaking
of Ps blocked in system calls. See #14790 for an example
of a program where execution time goes from 2ms to 30ms if
timeBeginPeriod(1) is not used.
We can remove timeBeginPeriod(1) when we support UMS (#7876).

Be more careful about inserting instrumentation in racewalk.
If the node being instrumented is an OAS, and it has a non-
empty Ninit, then append instrumentation to the Ninit list
rather than letting it be inserted before the OAS (and the
compilation of its init list). This deals with the case that
the Ninit list defines a variable used in the RHS of the OAS.
Fixes#15091.

Currently, there is no easy allocation-free way to turn a
[]byte or string into an io.Reader. Thus, we add a Reset method
to bytes.Reader and strings.Reader to allow the reuse of these
Readers with another []byte or string.
This is consistent with the fact that many standard library io.Readers
already support a Reset method of some type:
bufio.Reader
flate.Reader
gzip.Reader
zlib.Reader
debug/dwarf.LineReader
bytes.Buffer
crypto/rc4.Cipher
