yes, was curious why compression format didn't require

1. non compressed instructions are always 4 byte aligned (pad a 2 byte NOP if necessary, or use uncompressed 4 byte instruction to fix sizing)

2. jump targets are always 4 byte aligned (which exists without C, but C relaxes)

This avoids cache line issues & avoids jumps landing inside an instruction. Can consider each 2 compressed instructions as a single 4 byte instruction

Bit redundant to encode C prefix twice, so there's room to make use of that (take up less encoding space at least by having prefix be 2x as long), but not important
