detection that emits TRUNCATION annotations.

Fix incomplete assignment operators used in copy constructors; fix algorithm for detecting aliased mem writes in global DU chains.

Fix RTLs for SCAS and CMPS; eliminate spurious ERROR messages for LEA RTLs; reduce log messages to speed up; don't call profiler analysis methods if there are no profiler annotations.

Add USE/DEF of ESI to interrupt calls; eliminate duplicate PTRIMMED annotations for lea instructions.

Make add-with-carry and sub-with-borrow usually like add and sub, but with the possibility of changing the register type from POINTER to NUMERIC.

Continue building infrastructure to propagate memory DEFs until indirect writes create possible alias problems.
