Get internal numbers

Format: get v:S -> register:R/get instruction address:RN v:S -> register:R
Description: Gets an internal number and stores it in a register. In the left format, v is pc, sp, esp or fail (program counter, stack pointer, entity stack pointer, or failure flag). In the right format, v is low or high, because instructions are 32 bits and a register is only 16.
Cycles: 1
Example: get pc -> r0/get instruction 0x100 high -> r0
