[lworld] Clean up compiler test cases

[Ioi Lam]

I found that 7 valhalla tests for the compiler[1] have many very
long @run command-lines [2].

The reason for having these @run cases is to test with different VM
options. However, it's very difficult to maintain, especially when they
are copied several times and are subsequently modified independently.

I wrote a script to analyze the options [3]. If no one objects, I will
refactor these tests to replace these @run lines with something more
manageable.

Thanks
