Convert lit tests to check disassembled assembly.

tests_lit/llvm2ice_tests/fpconst.pnacl.ll

 ; This is a smoke test for floating-point constant pooling.  It tests
 ; pooling of various float and double constants (including positive
 ; and negative NaN) within functions and across functions.  Note that
 ; in LLVM bitcode, hex constants are used for an FP constant whenever
 ; the constant "cannot be represented as a decimal floating point
 ; number in a reasonable number of digits".  See
 ; http://llvm.org/docs/LangRef.html#simple-constants .
