Subject: [PATCH] test: convert issue 831 regression test to lit test

Move the 
ust_sdk_invalid_stack_offset_movup_16_issue_831 integration
test to a lit test suite under 	ests/lit/swapp/.

- Add codegen_succeeds.masm to verify compilation produces no errors
- Add issue831.masm to specifically check for the movup.16 stack offset
  regression
- Move the test fixture project to 	ests/lit/swapp/test-project/
- Remove the old integration test function from 
ust_sdk/mod.rs

Closes #875
