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 ab4c9298. 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.

Thus, we add a Reset method to bytes.Reader and strings.Reader to allow the reuse of these Readers with another []byte or string.
