[optimizing] Fold HTypeConversion of constants

While looking into optimizing long shifts on x86, I found that the
compiler wasn't folding HTypeConversion of constants.  Add simple
conversions of constants, taking care of float/double values
with NaNs and small/large values, ensuring Java conversion semantics.

Add checker cases to see that constant folding of HTypeConversion is
done.

Ensure 422-type-conversion type conversion routiness don't get
inlined to avoid compile time folding.
