Disable sign extension in SignExtLowering.cpp (#5676)
* Disable sign extension in SignExtLowering.cpp
The sign extension lowering pass would previously lower away the sign extension
instructions, but it wouldn't disable the sign extension feature, so follow-on
passes such as optimize-instructions could reintroduce sign extension
instructions.
Fix the pass to disable the sign extension feature to prevent sign extension
instructions from being reintroduced later.
* update pass description
