MPS issue job003741

Titlempsw3.h is unnecessary
Assigned userGareth Rees
Descriptionmpsw3.h [1] has never been documented; mps_tramp() is deprecated [2] so there is no need to provide an efficient implementation; and in any case we don't use Windows Structured Exception Handling any more [3] so it can't work any more.
AnalysisOpen Dylan is including this header [4]. But only on Windows, and on Windows they are stuck on release 1.108 [5]. So it won't hurt them to remove it: as part of the modernization procedure they need to remove it anyway.

So this header should be deleted to simplify the interface and avoid people accidentally getting the SEH version of exception handling.

Note that after deleting mpsw3.h, there'll be no need for the lines

    /* "Structured Exception Handling is not portable." (mps_tramp). */
    #pragma warn(disable: 2008)

in testlib.h.
