9c1f917e3a * a_call_ref functionality cannot be implemented efficiently at code generator level, because references need specific preparations at earlier points. Moved this support to tcgcallnode and its x86 descendants, and got rid of all ifdef's around.
+ x86 targets now directly call procedure variables located in references.
- a_call_ref method removed from tcg and thlcgobj.

a5d5ce8eb2 * TP-style object destructors do not need actual VMT in hidden parameter, a constant flag indicating need to free memory is sufficient.
* Destructor called from exception block in constructor must have this flag set in order to free memory.

07b2982e77 Don't do ARM FoldShiftLdrStr peephole optimization if there's an offset in the reference.
Use UXTH+UXTB instructions instead of two shifts on processors that supports that.
Eliminate internalerror when constant pointers are typecast as arrays.

81517fdf70 Rerun peephole optimizers on the whole block
Up until now if a peephole optimizer matched we've only restarted from
the current instruction. This patch restarts optimizations on the whole
block if the previous run had at least one match.

As this can take considerable time this will only be enabled if -O3 or
higher is specified.

57ff589ec7 Always set p to the next instruction after removing p from asml.
Some time ago we introduced GetNextInstructionUsingReg, which might
return an instruction a couple of instructions away from our current
location. Most of the code then just returned the new instruction (hp1)
instead of the instruction following p. This could prevent the peephole
optimizer from finding possible optimizations.
