pkg/compiler: optimize array[const] representation
Represent array[const[X, int8], N] as string["XX...X"].
This replaces potentially huge number of:
NONFAILING(*(uint8_t*)0x2000126c = 0);
NONFAILING(*(uint8_t*)0x2000126d = 0);
NONFAILING(*(uint8_t*)0x2000126e = 0);
with a single memcpy. In one reproducer we had 3991 such lines.
Also replace memcpy's with memset's when possible.
Update #1070
