Enhance #1426 "Invalid recursive :stmt expansion in fragment specifiers" test case
... that was recently added in #1429 commit 9fc6a27b5c6ea2c775646c4474b9084da76b1764 "expand: correctly handles non-macro nodes ...".
- Rename 'macro-issue1403.rs' -> 'macro-issue1426.rs'.
- Get rid of '-w'; expect diagnostic instead.
- Get rid of debugging options not relevant here.
- Get rid of explicit '-O1'; make it a "torture" test case.
- Replace always-matching 'scan-assembler "14"' ("14" appears in the crate name) with directed dump scanning.
- ..., just not for '-O0', where such optimization is not done.
