Convert lit tests to check disassembled assembly.

tests_lit/llvm2ice_tests/select-opt.ll

 ; Simple test of the select instruction.  The CHECK lines are only
 ; checking for basic instruction patterns that should be present
 ; regardless of the optimization level, so there are no special OPTM1
 ; match lines.
