fixes a longstanding bug which causes a "Nonparity Synchronous Error" kernel panic while using a debugger on Solaris / SunOS systems. The panic would occur on the first attempt to single-step the process.
The problem stems from an lda instruction on ASI_USERTXT (8). This asi was not being resolved correctly by resolve_asi().
