| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | in the test suite to fail. Restoring just 2 SetLineInformation() calls fixes those failures. The need for all the other SLI() calls is not demonstrated by any test. Without more complete test coverage, it is difficult to confidently tweak the TIP 280 implementation without fear that changes are introducing breakage.

| | | | | | | | | | | | | | | | | | | | Mostly these are just simplifications, removing code that wasn't needed. Some changes make the stack depth estimate more accurate instruction by instruction.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | their INST_*_STK* counterparts. Having done that, it is clear the "simpleVarName" return from TclPushVarName provides nothing of use to any of its callers. Eliminate that. Also make TPVN return void, instead of int. Bring the TPVN header comments up to date; they were quite rotten.
