TODO: Support NSDecimal "primitive" type.

[trevorlinton]

This may be an issue in ref-struct, NSDecimal fails to parse into a struct (well it does, but size=0). It's signature looks like this (from method_getReturnTypes) {?=b8b4b1b1b18[8S]}

The definition in apples docs say:

typedef struct {
      signed int _exponent:8;
      unsigned int _length:4;
      unsigned int _isNegative:1;
      unsigned int _isCompact:1;
      unsigned int _reserved:18;
      unsigned short _mantissa[NSDecimalMaxSize];
} NSDecimal;

This is listed as a primitive in the apple docs.. :/

Wait... I don't even get what's going on with the numbers on the right... Is that like manually setting the padding or something?

@TooTallNate They're bit fields, it treats the signed/unsigned ints only with as many bits as specified after the colon. The structure is meant to fit in a register so it can be passed by value, but is an awkward version of a Float/Decimal that can be used for money that doesn't have specific types of overruns. Effectively we can just treat it as a structure...

I need to implement this in ref-struct :)
