[decomp] allow #f to be used as a static pointer

[xTVaser]

Not sure if this was already fixed.

The hud-parts type is not a collection of basics, rather it is a collection of (pointer process), more specifically the processes correspond to the similarly named types.

The global var is initialized from a label with the value:

L1:
    .symbol #f
    .symbol #f
    .symbol #f
    .symbol #f
    .symbol #f
    .symbol #f
    .symbol #f
    .symbol #f
    .symbol #f

Which results in uncompilable code
