title: add a lightweight native pointer type to enable (non-compliant) built-in size optimization
desc: |-
  For 32-bit platforms the 8-byte tagged type can point to a C function directly,
  and has 16 bits free to provide additional metadata, such as function argument
  count or 'length' property.
  
  These lightweight function values could be used to optimize the memory usage of
  built-ins: there are about 180 built-ins now, each taking ~90-100 bytes, for a
  total of 16-20 kB.  A lightweight function pointer would make the functions
  strictly non-compliant (as they might not have the exactly correct properties
  and new properties could not be added) but would drop "hello world" footprint
  by almost 20 kB.
  
  A lightweight function values might also be useful for many C programmers,
  as often it's not that important what properties functions have.
