uint16_mult:

/**
 * Implement assembly code for this C function:
 *   uint16_t uint16_mult(uint16_t i1, uint16_t i2);
 *
 * This function performs 16-bit unsigned integer multiplication of @a
 * i1 and @a i2, returning the 32-bit product.
 *
 * SPECIAL RESTRICTION: You may only use addition, subtraction,
 * shifts, rotate, bitmasks, compare, and branch operations. You
 * <strong>may not</strong> use any built-in multiplication, division,
 * nor modulo division instructions for this part.
 *
 * As a reminder, ULNAv2-C uses this calling convention:
 *   R0 - holds first function parameter, and holds return value
 *   R1 - holds second function parameter
 *   R2-R5 - callee saved
 *   R6 - stack pointer
 *   R7 - link register (holds return address)
 * You are responsible for preserving registers R2-R5, and restoring
 * the stack when you are done.
