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)

c38508c262 introduced repeat loop. repeat-until changed to do-util.

struct literal is now same as array literal [...] to avoid parsing ambiguity with scope blocks.

3a99115070 Initial variable values semantics changed: now always sets value at program (re)start (except strings/arrays).
This may change later by introducing a compiler option to choose a strategy, perhaps.
