Clean up run script to use for testing Subzero.

tests_lit/llvm2ice_tests/vector-bitcast.ll

 ; This file tests bitcasts of vector type. For most operations, these
 ; should be lowered to a no-op on -O2.
 
 ; TODO(jvoung): fix extra "CALLTARGETS" run. The llvm-objdump symbolizer
 ; doesn't know how to symbolize non-section-local functions.
 ; The newer LLVM 3.6 one does work, but watch out for other bugs.
