Add the ARM32 FP register table entries, simple arith, and args.

tests_lit/llvm2ice_tests/fp.arith.ll

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