Change some tests to be valid PNaCl IR (parameter type from i1 -> i32).

tests_lit/llvm2ice_tests/fp.pnacl.ll

 ; This tries to be a comprehensive test of f32 and f64 operations.
 ; 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.
