7dbff5b9e6 abs: remove support for floats. Use floats.fabs() instead.
this solves: can't use abs() etc in pipe expression because return type depends on argument type

220246278a removed sum(), max(), min(). abs() now always returns uword type.
This greatly simplifies internal handling of builtin functions by always having one fixed return type.

928611eb20 Got rid of problematic attempts to save status register after function calls. If you really need it (for instance for if_XX instructions) it's probably better to use a short asmsub wrapper.
For function calls, register saves go via stack (to allow nested saves) for simpler cases, registers are saved in a local variable.
Fixed too agressive removal of sta-lda sequence if the lda is followed by a branching instruction.
Insert missing cmp #0 after functioncall if the value of the A register is needed in a comparison expression (could otherwise test wrong status flag)
