Reverse the voiceno counter: now it starts from MAX_VOICES and decrements until 0. This way, the VM needs not know anything about MAX_VOICES.

Implement support for 64-bit builds.
...
The implentation is through a few macros to handle the fact in 64-bit, all addresses have to be loaded first to register and only offsets are ok. Also, push only supports 64-bit registers in 64-bit, so we have _AX, _BX, _CX etc. defines, which are eax, ebx and ecx on 32bit and rax, rbx and rcx on 64bit.

Rewrote most of the synth to better support stereo signals and polyphony. VSTi removed as there is no plan to update the VSTi to support the new features.
...
The stereo opcode variants have bit 1 of the command stream set. The polyphony is split into two parts: 1) polyphony, meaning that voices reuse the same opcodes; 2) multitrack voices, meaning that a track triggers more than voice. They both can be flexible defined in any combinations: for example voice 1 and 2 can be triggered by track 1 and use instrument 1, and voice 3 by track 2/instrument 2 and voice 4 by track 3/instrument 2. This is achieved through the use of bitmasks: in the aforementioned example, bit 1 of su_voicetrack_bitmask would be set, meaning "the voice after voice #1 will be triggered by the same track". On the other hand, bits 1 and 3 of su_polyphony_bitmask would be set to indicate that "the voices after #1 and #3 will reuse the same instruments".

Refactor all values to have a universal support for modulations.
...
The modulation is now always added during value transformation.
With this, a lot of *_MOD defines could be removed.
The waveform for some tests changed slightly, because when the
value is saved to memory after modulating it, there is some
rounding errors.
